It's a silly idea to say that DM is destroying other clans and preventing them from growing and being happy. A clan is what it's own members make of it. Please name some clans that have been deprived of happiness just because of DM's existence.

As for J2O, JCF and JDC "tyranny": would you prefer people attacking and flaming each other, cheating, giving bad reviews just because they don't like the person who posted a download? Without anyone even trying to stop it? If you're just nice to each other, and leave those who you don't like alone, i'd say you're not very likely to get banned from anything. If you feel attacked on J2O and can't resolve the matter with the person, just contact an admin, don't start flaming each other in public. If it is a DM member you're having problems with and don't trust the other DMs, you might think of contacting a non-DM admin. Really, they exist. Or, even more simple, ask a reasonable friend who isn't an enemy of either side to have a talk with the other party. Someone neutral can be a big help in cases like this. And it's not really like they ban someone for one error. If they did, 90% of the community would be gone already. They don't even give real warnings (the sort that can get you banned) as easily as you might think. There are plenty of things that might've deserved a warning (including some stuff i wrote myself in the past), but didn't get one. So i wouldn't say the community is run by a bunch of tyrants bent on destroying fun for jj2 players. They're just humans like you and me, who go to quite some trouble to make the best out of this community. So don't be too quick to call them tyrants and other nice things like that. The community would look a LOT different without them, probably not in a positive way...
