You either help or hurt Toribash when you make a decision like this. The question becomes do, as a community, we feel that some clans are too important to destroy no matter the inactivity. We are not Clan Mods, we do not actually have a say, but we do have an opinion and I think it's worth sharing it on this subject.
I don't know where the line is. I can say I'm very comfortable with [bncy] getting deleted because despite me associating that clan with the likes of Ishi and War_Hero, they aren't impacting the community anymore. They aren't entering events, they aren't logging onto Toribash, they aren't using the forums, they aren't using their board.
But then look at the extreme contrast from [bncy] to [RAWR]. RAWR does enter events, they are in Clan League every year. RAWR does have active forum members, I can't go a day without reading something written by BenDover. RAWR does still impact the community, people actually play Toribash explicitly because of work Nuthug's done. To me, all of that, combined with the amount of hours the members of RAWR have put in at one point or another making Toribash a better place whether it be as role models or as staff members is enough to not touch the clan. It's the reason a clan like MAD exists.
The juice has to be worth the squeeze. I don't think the "juice" here being we get to free up an official clan spot (which are limitless from what I can tell) is worth the "squeeze" of disbanding clans with friendships that have lasted longer than most people's time here in Toribash.
