I used to hate on bandit goons but now I just abandoned my staff morals and simply abuse my pex to dodge them...

Jokes aside, I know how frustrating it can be to endure someone else having a power-trip over humiliating your persona but then again, it's a game and if you don't treat it as such you'll suffer and succumb to frustration. In a sense, you have to let your persona go free, only then there is room for character development (This counts for characters of any occupation, be it villainy or something else). Now a good step in the right direction is to refrain from stalling RP by constantly barraging others OOC. Another good measure is not to be fixated on loot or whatever pixels you might deem valuable.
One thing however, for aggressors. Please try not to break immersion during bandit/villain RP, if there's one thing I've seen escalate things it's dispelling the premium mineman illusion.
