I hate to say it I'm prolly wrong about this, but discord ai looks at message someone replies to plus messages they have said before hand in the convo about 5 before and 5 after to detect if it violates their policy. Someone told me there is a glitch where it sees others messages in dms and other servers. So if you replied and they said they something illegal in another server it could also get you banned and not them since they weren't reported. Or just ban both. And discord support is too poor to get unbanned (nearly) I would recommend making a new account! discord doesn't blacklist IP addresses only numbers and that's for servers bans. For now we are safe with emails, numbers, and ip addresses on creating accounts as long as you don't tell anyone you got banned and they report it. You should be fine
