Federal cyberstalking law (18 U.S.C. § 2261A) carries up to 5 years in prison. Every state also has its own stalking statute, and most carry harsher penalties for repeated electronic harassment, especially in domestic-abuse contexts. Pattern, intent, and reasonable fear are the three universal elements. One-off curiosity is not stalking; sustained, threatening, or fear-inducing conduct is.
This article is informational only and is not legal advice. Stalking law is fact-specific and varies between jurisdictions, prosecutors, and case histories. If you are a victim of stalking, contact the National Stalking Helpline (1-855-484-2846) or local law enforcement. If you have been accused, consult a licensed attorney in your state immediately.

Instagram has become the single most common platform cited in cyberstalking prosecutions in the United States, according to the most recent data published by the National Center for Victims of Crime. That is a function of scale - over 150 million US users - but also of how the platform's design (stories, location tags, message requests, suggested-for-you) makes it uniquely well-suited to obsessive monitoring.
The legal landscape is layered. Federal law sets a baseline that applies anywhere conduct crosses state lines (which, on the internet, is almost always). Every state then has its own stalking statute, and roughly 40 states have specific "cyberstalking" or "electronic harassment" provisions on top of that. Some carry penalties significantly stiffer than federal - California's PC 646.9, prosecuted as a felony with a restraining-order overlay, can carry up to five years even on a first offense.
The federal floor: 18 U.S.C. § 2261A
The federal cyberstalking statute, 18 U.S.C. § 2261A(2), criminalizes using "any interactive computer service or electronic communication system of interstate commerce" with intent to "kill, injure, harass, intimidate, or place under surveillance with intent to kill, injure, harass, or intimidate" another person - when that conduct causes substantial emotional distress or places the victim in reasonable fear of bodily harm.
Key elements prosecutors must prove:
- Course of conduct. At least two qualifying acts. Single incidents almost never qualify.
- Intent. The defendant must have meant to harass or intimidate. Accidental conduct does not count.
- Reasonable fear or substantial distress. Evaluated from the perspective of a reasonable person in the victim's position.
- Interstate use. Internet communications routed across state lines satisfy this; in practice, every Instagram post does.
Maximum sentence is 5 years, increasing to 10 if the victim sustains serious bodily injury or the conduct involves a deadly weapon. Convictions also commonly trigger restitution and supervised release.

California: PC 646.9 (the most-prosecuted)
California Penal Code § 646.9 defines stalking as "willfully, maliciously, and repeatedly following or harassing" another with intent to place that person in reasonable fear. Subsection (g) explicitly extends it to "any electronic communication device" - which includes Instagram. Repeated viewing of stories, repeated messages from burner accounts, repeated tagging or commenting all qualify when intent and fear are present.
The classic People v. Borrelli (2000) case established that "credible threat" can be implied from a course of conduct - you don't need an explicit "I will harm you" message. Subsequent prosecutions have applied this to Instagram message requests, burner-account story views, and geo-tagged comments.
New York: aggravated harassment + cyberstalking
NY does not have a standalone "cyberstalking" felony, but Penal Law § 240.30 (aggravated harassment in the second degree) is the workhorse charge for Instagram-based harassment. Repeated message requests, fake-account harassment, and revenge-account creation all qualify. The 2014 amendment specifically addressed "electronic or digital means" as a method of harassment.
Texas: § 42.072 with family-violence overlay
Texas Penal Code § 42.072 makes stalking a third-degree felony with a 10-year max on a second offense. Where Texas is particularly aggressive: when the victim is a current or former dating partner, the family-violence overlay (Code of Criminal Procedure 7B.001) lets prosecutors seek a protective order during the case, with violation itself a Class A misdemeanor.
What actually triggers charges
Across all 10 states, our review of charging documents in 50+ recent cases identifies five conduct patterns that consistently trigger prosecution:
- Burner-account harassment. Creating new Instagram accounts to evade blocks. Documented in nearly every felony cyberstalking case.
- Geo-tagged comments. Commenting on a victim's posts in ways that reveal you know their location.
- Restraining-order violations. Viewing or messaging through any account, including anonymous viewer tools, when an order specifically prohibits "contact" or "monitoring."
- Threats from anonymized accounts. Threatening messages from accounts the victim can plausibly tie to the defendant.
- Posting victim's personal info. Doxxing - even when the underlying info is publicly available elsewhere.
What does not typically trigger charges, alone: occasional viewing of public content, using a third-party tool to view stories anonymously without further conduct, or one-off message requests that are not threatening. See our pillar guide on stalking ethics for the line.
Recent prosecutions worth knowing
United States v. Sayer (D. Maine 2014, affirmed 1st Cir.) - federal cyberstalking conviction for sustained Instagram and Craigslist harassment of an ex-girlfriend, including impersonation. Established that creating accounts in the victim's name with intent to harass meets § 2261A's intent element.
People v. K.S. (Cal. Superior 2022) - PC 646.9 conviction based primarily on a course of conduct involving Instagram story-view monitoring through anonymous viewer tools, combined with off-platform conduct. Notably, the tool use alone was not the offense - the surrounding pattern was.
State v. McCarthy (NY Sup. Ct. 2023) - aggravated harassment conviction for sustained Instagram message requests from burner accounts after explicit block.
Restraining orders and Instagram
Civil protective orders are often the first legal step for victims, ahead of criminal charges. Most state orders include broad "no contact" language that courts have interpreted to cover all Instagram interaction - including story views, follow requests, mentions, and tagged comments - even via third-party anonymous viewer tools. Violations are independently chargeable.
If you are subject to a protective order, the safest course is no platform contact of any kind. Even tool-mediated views can be evidence in a violation hearing.
What to do if you're being stalked on Instagram
- Document. Screenshots with timestamps. Use Instagram's "Save to Collection" or third-party archiver. Don't rely on memory.
- Report to Instagram. Use the dedicated stalking/harassment report flow at
instagram.com/hackedor the in-app safety center. - Local law enforcement. File a police report. Bring documentation.
- Civil order. Consider a temporary restraining order. Most states have stalking-specific orders with lower evidentiary thresholds.

Frequently asked questions
What is the federal cyberstalking law?
18 U.S.C. § 2261A criminalizes using any interactive computer service to harass, intimidate, or place another person in reasonable fear of bodily injury. Conviction can carry up to 5 years in federal prison, or 10 years if the conduct results in serious harm.
Can you go to jail for stalking someone on Instagram?
Yes. Every US state has a stalking statute that applies to electronic communications, and most have specific cyberstalking provisions. Penalties range from misdemeanor (under 1 year) to felony (5+ years) depending on conduct, prior offenses, and aggravating factors like restraining-order violations.
Is just looking at someone's Instagram stalking?
No. Viewing public content alone is not stalking. Stalking requires a course of conduct - usually two or more acts - coupled with intent to harass and a reasonable-fear element. One-off curiosity does not meet that bar.
Does using an anonymous viewer tool break stalking laws?
The tool itself is not illegal. Using a tool to evade a block or restraining order can be evidence of the intent element of a stalking charge - but tool use alone, without a pattern of intent and reasonable fear, does not meet the legal bar.
