Electronic harassment laws in Illinois make it a crime to use email, text messages, social media, or other digital channels to harass, threaten, or alarm another person. A single incident can be charged as a Class B misdemeanor carrying up to six months in jail, while repeated conduct or threats of physical harm can be charged as cyberstalking, a felony that starts at one to three years in prison and climbs from there. The statute that applies depends on what was sent, how often it was sent, and whether a reasonable person would have been put in fear.
What Counts as Harassment Through Electronic Communications
The core statute is 720 ILCS 5/26.5-3, which targets harassment carried out through digital channels. To secure a conviction, prosecutors have to prove the sender acted with the intent to harass, annoy, or alarm the recipient. A message that simply landed badly is not enough; the state must show the sender meant to cause the effect.
The statute reaches several specific behaviors: sending obscene or threatening messages, knowingly transmitting false information to harass someone, and making repeated unwanted electronic contact. That last category matters, because a single rude email and a weeks-long campaign of unwanted texts are treated very differently. Courts weigh content, context, and the relationship between the parties when deciding whether a pattern of contact crosses the line a reasonable person would find distressing.
A first offense with no aggravating factors is a Class B misdemeanor, punishable by up to six months in jail and a fine of up to $1,500.1Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-60 – Class B Misdemeanor A judge can impose probation, community service, or mandatory counseling in place of jail. The classification sits toward the lower end of Illinois criminal charges, but a conviction still creates a permanent record.
When It Becomes Cyberstalking
Once the conduct repeats or involves threats, Illinois prosecutors can charge the far more serious offense of cyberstalking under 720 ILCS 5/12-7.5. Cyberstalking is a felony from the first conviction. It requires a “course of conduct,” meaning electronic contact on at least two separate occasions, and the conduct must be the kind that would cause a reasonable person to fear for their safety or suffer serious emotional distress.2Illinois General Assembly. Illinois Code 720 ILCS 5/12-7.5 – Cyberstalking
The statute describes four ways someone can commit cyberstalking:
- Transmitting threats of bodily harm, sexual assault, or confinement, directed at the victim or a family member, on two or more occasions.
- Making repeated electronic contact that places the victim or a family member in reasonable fear of physical harm.
- Secretly installing monitoring software on someone’s device to facilitate harassment or threats. The statute carves out an exception when the device’s owner or primary user has received clear advance notice or given written consent.
- Creating and maintaining a website or webpage, accessible to third parties for at least 24 hours, that contains harassing statements paired with threats or conduct that places the victim in fear.
A first cyberstalking conviction is a Class 4 felony, carrying one to three years in prison.3FindLaw. Illinois Code 730 ILCS 5/5-4.5-45 – Class 4 Felony A second or later conviction becomes a Class 3 felony, which carries two to five years.4Illinois General Assembly. Illinois Code 730 ILCS 5/5-4.5-40 – Class 3 Felony Fines up to $25,000 apply at both levels, and courts can add restraining orders and electronic monitoring to keep the defendant away from the victim.
When Federal Charges Can Apply
Electronic harassment that crosses state lines can also draw federal charges, often alongside the Illinois case. Under 18 U.S.C. ยง 2261A, federal jurisdiction attaches when someone uses the internet, email, or any electronic communication service that operates across state lines to stalk or harass another person.5Office of the Law Revision Counsel. 18 U.S. Code 2261A – Stalking Because almost all internet and phone traffic travels through interstate infrastructure, this threshold is easier to meet than it sounds.
Federal penalties run well above the Illinois maximums. A baseline federal cyberstalking conviction carries up to five years in prison. Serious bodily injury to the victim raises the maximum to ten years. Permanent disfigurement or a life-threatening injury pushes it to twenty years, and if the victim dies, the maximum is life.5Office of the Law Revision Counsel. 18 U.S. Code 2261A – Stalking Anyone who violates the federal statute while subject to a restraining order or no-contact order faces a mandatory minimum of one year.
Protection Orders Victims Can Seek
Victims do not have to wait for criminal charges to get protection. The Stalking No Contact Order Act (740 ILCS 21) lets someone experiencing stalking or cyberstalking petition a civil court for an order barring the harasser from contact. Because it is civil, the burden of proof is a preponderance of the evidence rather than proof beyond a reasonable doubt.
This remedy fills a real gap. An Order of Protection in Illinois requires a specific relationship between the parties, such as family members, household members, or dating partners.6Illinois Attorney General. Filing Protection Orders A Stalking No Contact Order has no such requirement, so it is available to people harassed by strangers, acquaintances, coworkers, or anyone else outside those domestic categories. Violating the order is itself a crime, which is what gives it force.
Civil Lawsuits for Emotional Distress
A harasser can also be sued. The most common claim is intentional infliction of emotional distress. The plaintiff has to prove three things: the defendant’s conduct was truly extreme and outrageous, the defendant intended to cause severe emotional distress or knew there was a high probability it would result, and the plaintiff actually suffered severe emotional distress.7Illinois Courts. Feltmeier v. Feltmeier
The bar is deliberately high. A few nasty emails will not meet it. A sustained campaign of threatening or degrading messages aimed at destroying someone’s sense of safety is the kind of conduct Illinois courts find actionable. A successful suit can produce damages for therapy costs, lost wages, and emotional suffering, which is a financial remedy that a criminal prosecution does not provide.
Defenses to a Harassment Charge
The most direct defense is challenging intent. Every harassment and cyberstalking statute in Illinois requires the state to prove the defendant acted for the purpose of harassing, threatening, or alarming the victim. If a message was misinterpreted, was part of a mutual argument, or lacked any real malicious purpose, that element may not hold up. Defense attorneys look at the history between the parties, the tone and content of the messages, and whether the record actually shows one-sided harassment or a two-way dispute.
The First Amendment is a second line of defense, though narrower than many defendants expect. Speech that qualifies as a “true threat” or conduct meant to cause harm is not protected. The Illinois Supreme Court recognized in People v. Relerford that parts of the state’s stalking and cyberstalking statutes reached too far. The court struck down language that criminalized communicating “to or about” a person when the speaker should have known the communication would cause emotional distress, finding it swept in too much ordinary speech and was unconstitutionally overbroad.8Justia Law. People v. Relerford That ruling limits how aggressively prosecutors can apply the emotional-distress prong, especially where the speech involves matters of public concern.
Illinois law also carves out communications made during lawful business activities and constitutionally protected speech. Debt collectors making repeated contact, attorneys communicating about legal proceedings, and journalists covering stories can all fall within these exceptions. The defense can argue the communication served a legitimate purpose, however unwelcome it was.
Consequences Beyond Jail and Fines
The statutory penalties are only part of what a conviction costs. A record for electronic harassment or cyberstalking shows up on background checks for employment, housing, and education. A felony cyberstalking conviction is particularly damaging, because Illinois employers and landlords commonly run criminal history checks and a felony can disqualify an applicant outright.
For licensed professionals, the consequences can end a career. The Illinois Department of Financial and Professional Regulation can investigate any criminal conviction tied to a licensee and impose discipline ranging from a reprimand to full revocation.9Illinois Department of Financial and Professional Regulation. Statewide Enforcement Section Teachers, nurses, attorneys, and real estate agents all face the possibility that a harassment conviction triggers a separate disciplinary proceeding with their licensing board. Even when the sentence is light, losing the right to work in your profession can be the heaviest consequence of all.
