Got banned on cb for roleplay (sister’s friend)

[Frolickinded]

So I got banned from cb for playing a rp (sister’s friend) they emailed me the reason as it is !nce5t . I explained what I was playing and they unbanned. This doesn’t make sense, is there a way to play a rp that doesn’t violate their TOS and not get banned? Or do I have to write explaining what I was trying to do everytime to get it unbanned?
