Tiktok creeps?

I have a small following on tiktok (abt 4k) because I post outfit videos, and some of my mutuals have upwards of 50k-300k. I’ve been seeing accounts in their comments asking if “they have any videos” or “name?”, and the comments and accounts all look very similar, with a very similar following. Today I saw one on a celebrity’s post. I’m pretty sure they’re encrypted images but I want to make sure, and I also want to know why they’re choosing random women? It’s dark to think about but why would they have anything online at all? is it AI material their after? I just have so many questions. It became a real concern after seeing a girl I regularly interact with and look up to in a way have 3 of these individual accounts conversing with one another in her comments.
