Hi Amanda, unfortunately I don't think there is an easy way to do this across all the platforms, as they have different privacy and security rules, with some of the platforms adopting the "blue checkmark" its a little easier when dealing with high profile accounts.  For X and Li you can use Sprinklr's Profile Impersonation Report

Here's a check list of some other things you can do:

1. Check the profile details

• Weird usernames (lots of random letters/numbers)
• Stock or stolen profile pics (try a reverse image search)
• Empty or super generic bios
• Hardly any original posts
• New account with sketchy activity

2. Watch for suspicious behavior

• Big follower spikes with low engagement
• Spammy or off-topic comments
• Following thousands, but barely followed back
• No verification badge (for public figures/brands)

3. Use tools to dig deeper

• Fake follower checkers like FakeCheck.co or Followeraudit
• Reverse image search (Google Images, TinEye)
• Cross-platform check – see if the account looks legit across other platforms
• Engagement quality – real comments vs. bot-like spam
• TikTok influencer tip – ask for audience insights before partnering

4. Report suspicious accounts

• Use the platform’s report feature
• Include screenshots and any proof you’ve gathered

Hope this helps!
