Hey @SignalRanger, I’ve been in a similar spot before, trying to figure out who’s behind a TikTok account. One tool I tried is Scannero. It has a username reverse lookup which can give you info if that username is used elsewhere, and sometimes you get lucky and find more about the person. They also have phone lookups and even basic location tracking, but results vary and it doesn’t always work if the info isn’t public somewhere.
If you’re curious, here’s where I used it:
Hope that helps! Just be careful with any tool promising too much, and always respect privacy rules.
