tos violation?

trying to upload photos and review models that I've accessed, but they all say TOS violation. what violation? how?

I was trying to find the TOS - where can you see them? but also - I don't believe they were explicitly against the TOS.

Have you read the ToS? Most images removed for breaking the ToS appear to depict underage subjects, or include NSFW of real-world people. I can't say why yours were removed I'm afraid. You could try uploading a second time.
