[Discussion] Do you get banned if you get unicorn chomp via a mod?

To my knowledge, any mod that adds Unicorn Chomper will add it to your roster permanently even when the mod is removed since they're a native character to the game. As longer as the mod isn't malware or something, you should be fine.

Supposedly there's also a way to add them in the files, may need a decompiler/programming knowledge though.
