I don't think the problem here is individual players and their antagonist characters.
I think the problem is a broader issue of people playing antagonistically and then staff denying their antagonism is happening.
The 'examples' given by staff of problem players refer to those outside the ruling clique.
They don't encompass the problem players within the clique. Now I don't play there, so I'm just going to take a wild guess and say the clique includes:
Oblivious meathead - This person plays a violent, abrasive meathead character. Hoo-ah. OOCly they see nothing wrong with their character's actions and neither does their clique because 'lol he is a good rper and you just don't understand.' Usually a typical generic whitebread male character with few defining personality traits aside from those mentioned.
Oversensitive whiner - This person is militantly triggered by everything and oh my god people are so mean! Of course, this only includes things said by those outside the clique. When the clique members do the same things they just say 'lol they are just joking and you don't understand'. Most often an effeminate, stereotypically gay character.
Spotty McSpotlighterson - This person's character saves the day! They are in charge! They're the focus of the story! They only do it because nobody else steps up though. If they didn't, nobody else would! They're not a problem, you're the problem for thinking they're the problem! This one varies but is almost always a staff alt of some sort and usually somehow has more stats or XP than anyone else.
Bitchy Queen Bee - All other female characters are played by bitches and they deserve to be the victims of cattiness OOCly from Bitchy Queen Bee. BQB doesn't mean those hurtful, snide things she says! She's just joking! Really! I mean Becky is kind of a slut and Tracy is a bitch but lol, am I right? Tends to use 'pretty but generic' PBs and plays characters that are 'sweet' or 'kind' or 'nice' while behaving manipulatively OOCly.
...am I pretty warm with these stereotypes? I'm willing to bet that names immediately pop into mind for those of you who play the game.
