here's the problem with thucy's method:
Everyone would agree not to interact with that person, something on the list gets posted, it cheeses off one person, they go and respond, then the thread gets full of people defending the "victim", or bitching that they shouldn't respond (even though they are making it worse by responding), and the discussion devolves into a shitstorm.
Why do I know this will happen? Cause every damn person on the site knows how not to feed the trolls, yet half this forum is trolls with 100+ replies.
The only way self moderation would truly work is for every member to upvote and downvote forum posts. But, as krellin has said, this could cause corruption of the majority. Because if 80% of the members are pro-scub, and 20% are anti-scub, any anti-scub post will get downvoted along with stuff like ethnic slurs. Corruption.
The one thing I want to avoid is scaring away new players because our forum resembles 4chan. Kestas's idea (from my understanding) was to give people tools to mute the idiots... the problem is, most new users have to deal with EVERYTHING before even understanding how muting works. So it isn't tough for a new user to come on, see the ethnic slurs and personal attacks on the forum and decide this isn't the place for them.
I suspect one of 3 things happening, from most likely to least likely:
1.) The forum becomes a discussion of diplomacy related subjects, only.
2.) The forum becomes heavily moderated, which everyone will hate (because heavy moderation is biased and a lot of 'gray area' calls)
3.) The forum devolves into 4chan
4.) The forum cleans itself up on its own
Those are my thoughts.
