Why are comments folded?

I don't understand what causes tiktok to fold certain comments. Could anyone explain this to me? I always see this issue on a lot of other tiktok videos where certain comments are folded but are not offensive or spam in any sort of way.

Because it's says "i love my girls". it's way too strict and treats it as sexual or harmful comment.

This happens to me all the time… I have an account for my chronically ill cat, and on every single video, there’s at least 1 folded comment. It’s always something that’s 1000% appropriate. Mostly people sharing pictures of their pets, sometimes just a positive comment. But the actual terrible comments? They don’t get folded. I’ve had 2 people say something awful, and neither was folded. I hate it.
