How to Catch a Cheater on Instagram: 7 Proven Detection Methods
Suspecting a partner of cheating can be an emotional rollercoaster, and social media often makes it harder to trust.
Instagram, in particular, has become a hotspot for secret interactions and hidden affairs.
If you've noticed unusual behavior and want to confirm your suspicions without overstepping ethical boundaries, you're in the right place.
Below are seven proven methods to help you catch a cheater on Instagram without resorting to illegal or harmful actions.
How Can You Catch a Cheater on Instagram?
If you suspect your partner is cheating on Instagram, look for sudden changes in their social media behavior.
Some key red flags include:
- Deleting old couple photos or hiding stories from you
- Following new, unfamiliar accounts or frequently engaging with a specific person
- Flirty comments, excessive likes, or vanish mode in DMs
- Being secretive with their phone and Instagram messages
To investigate, monitor their followers and following lists, check their story access settings, and look for deleted tags or restricted accounts.
If you find consistent suspicious behavior, ask calm, open-ended questions to address your concerns.
You can also use tracking tools to check login locations and recent activity, but ethical communication is always the best approach.
For a detailed breakdown of these 7 proven methods, continue reading below. 🚀
1. Look for Changes in Their Online Behavior
Cheaters often exhibit subtle but noticeable changes in how they use social media.
If your partner suddenly stops posting pictures of you together or deletes old couple photos, it could be a red flag.
Additionally, an unexplained increase in followers and following new people—especially those of the opposite gender— can signal secretive interactions.
If they're liking and commenting more frequently on someone's posts, particularly with flirtatious emojis, it's worth noting.
📌 Action Step: Start taking screenshots of anything that seems off. Keeping a small record can help you uncover patterns.
2. Check Their Following & Followers List
One straightforward way to identify suspicious activity is by carefully examining who your partner follows and who follows them back.
Often, cheaters will follow private accounts that you don’t recognize or start interacting with a string of local profiles they weren't connected with before.
Pay close attention to connections with old exes or people they said they'd “cut off”.
If these accounts have private settings, and your partner seems to have ongoing engagement with them (likes, comments, or private messaging), this may be worth questioning.
📌 Action Step: Use an Instagram tracker or manually check their “Following” and “Followers” list daily for sudden changes.
3. Monitor Suspicious Comment Activity
Not everyone hides their flirty interactions in DMs. Some people drop subtle flirty comments openly on Instagram posts.
If someone frequently comments with heart emojis, flirty words, or inside jokes, your partner might be engaging in an inappropriate connection.
A sneaky move some cheaters use is flirting in comment replies or under non-obvious posts (like Instagram Story question boxes) to avoid being too obvious.
If your partner seems extra careful about comments disappearing, there’s a reason they don’t want you to see them.
📌 Action Step: Check their recent comment history on other profiles. Look for recurring engagement with a particular person.
4. Analyze Their Instagram Stories and Archives
Instagram Stories allow users to share fleeting moments, which disappear after 24 hours (unless saved in Highlights). Cheaters often use Stories because they feel temporary and easy to hide.
Look for habitual gaps in their social media activity—for example, do they post about their night out publicly but not mention who they were with?
If they block you from viewing certain Stories, that’s another red flag.
📌 Action Step: Use a second Instagram account or a friend's account to check if they have private Stories hidden from you.
5. Investigate Their Restricted Accounts and Tagged Photos
A lesser-known Instagram feature is the Restricted Accounts list, which allows users to hide certain interactions from others without blocking anyone.
If your partner has secret connections, they might restrict you from seeing likes or comments they leave on someone else’s profile.
Similarly, they might untag themselves from photos where they were out with someone they don’t want you knowing about.
If they used to be comfortable being tagged in random group photos but now seem extra cautious, that’s a warning sign.
📌 Action Step: Click the “Tagged Photos” tab on their profile and check what’s disappeared. If all-new shared photos suddenly go missing, investigate further.
6. Review Their Direct Messages & Message Requests
While you may not have direct access to your partner’s messages, behavioral changes in how they use the DM feature can indicate something fishy.
If they:
- Swipe out of Instagram whenever you're near
- Delete conversations quickly
- Start locking their phone more than usual
- Have “vanish mode” enabled in specific chats
These are classic signs they’re hiding something.
If they suddenly mute notifications for Instagram conversations, that’s another big clue.
📌 Action Step: While you can’t demand their password, you can notice if specific accounts appear in their “Recently Messaged” list but always have empty chats.
7. Use Tracking Tools or Confront Them Directly
If you’ve gathered enough suspicious activity and it’s affecting your peace of mind, you have two primary options:
- Use tracking tools that show login locations, login times, and suspicious interactions.
- Confront them by showing evidence in a non-aggressive way and asking for clarity.
Having a calm, clear conversation with proof makes it harder for them to deflect or gaslight.
Rather than accusing them outright, ask open-ended questions like:
🔹 “Hey, I noticed you’ve been interacting a lot with [name]. Are you two close?”
🔹 “I saw you restricted me from seeing some of your stories. Is there a reason?”
📌 Action Step: Before confronting them, review methods to catch a cheater that deletes everything to understand how people hide digital evidence.
