Clans are completely stupid. Clan members destroy each other's servers for sport, and some even attack servers that new players make. If your plan is to eradicate clans, I have one main solution for you.
Clans are powerless when they can't raid each other. Kicking doesn't work, as they just come right back. Banning would be perfect, so a ban option would most likely mark the end of clans. It could also open an opportunity for clans to be peaceful communities that are newbie-friendly, and consist of players just playing together for fun, instead of trying to conquer some other clan.
Anyway, PLEASE add this ban button. It's much needed in Sandbox to prevent against problematic players.
