My base line for dealing with any of the Eve-Online forums is to not post unless I've got a good reason.
^This.
It was my modus operandi for BloodBird and Jesmine when I played actively; don't say anything in public unless it's a legitimate comment and/or important to the topic at hand. Also, keep your private life private (out of the super-public sphere that is the IGS, unless it can't be helped) and make treads only when you have a good purpose for it. That is, when your toon needs to communicate something to the public that isn't best done by mail.
It also helped that both those toons were relatively polite and tended to look down on those that simply run their mouths and/or can't be rational and somewhat respectful even to their enemies. Hatred and conviction to fight and kill is well and good, (to the point where it gets good fights and more conflicts \o/ ) but the average foaming-mouth rager who can't stop being mad at [insert favorite target] got old and boring really, really fast.
While it's only my opinion, the most interesting and engaging toons I RP'ed with where those who managed a balance between personal and public opinions, beliefs and causes, and a modicum of healthy civil and... level-headed conduct. It's not good to play, say, an Amarrian hardliner while trying to remain bestfriendsforever with you enemies, but again, the opposite of being super-hostile and near programmed-for-eternal-hate-and-anger vs X wasn't very interesting either.
In short, it's complicated, and maintaining interesting and believable characters can become a challenge. Especially as everyone's definition of "interesting and believable" is different.
And add to this the general drop in RP'ers in recent years and the PF changes (or lack of them) and we got today's sad state of affairs. I'm honestly not entirely sure what can be done to try and remedy this situation.
