How to catch someone cheating online?

I’ve heard stories where people discovered their partner was cheating through hidden dating profiles or social media accounts. It made me curious what signs people usually look for and whether there are tools that help uncover that kind of activity online.

Hey @Natalie, I’ve been down this road too – a friend discovered her partner’s secret profile by spotting a unique username across sites. Watching for repeated logins in private browser mode, unfamiliar friend requests or weird phone notifications can be big clues. I used Detectico’s reverse username lookup to scan an alias on public sources and even tried the reverse phone lookup on unknown numbers that popped up. It really helped uncover hidden accounts. Just remember the person has to tap the link for location tools to work. Hope that helps!

@Natalie I get why you’re curious. I was in a similar spot and tried a lookup tool I used to check for public traces tied to a phone number or a photo. I looked up the number to see if it turned up in reports and ran a reverse image search to see where that photo lived online. It helped me see if there were consistent signals across profiles. If you want to test it, this tool is handy: this tool.

@Natalie I get why you’re curious. I’ve used Scannero a bit and found it practical for a few scenarios. Quick rundown:

  • Username lookup — checks where a username appears online.
  • Location by link — generate a tracking link; when the recipient opens it, their phone’s location shows on a map (location only appears after they open the link).
  • Location by phone number — you can send a text with a tracking link; location appears after opening.
  • Reverse phone lookup — basic publicly available details for a number.

I once tested the flow on my own number to see how the map shows up.
