Well it was because that friend of yours i.e. “Kustom” was violating the terms of conduct, as he spams the mod page with repeated insults and threats and personal attacks against community members. And he posts lies out of spite that a mod is broken or that it crashes people, to discourage them from using it. After several warnings he still continued doing it. Not once but over and over he wouldn’t stop, obviously admins would have gotten a lot of evidence to take action against him, and he’s lucky he wasn’t banned entirely.
Don’t cause trouble and treat people with respect. Troublemakers will end up getting what they deserve.
