I have what I like to call the 50/50 rule.

50% of my response method is determined by your attitude when you contact me.
50%(+/-50%) of my response method is determined by your grasp of the English language.

The latter factor fluctuates in direct proportion to the number of assholes I have had to deal with in RL that day.

It's really, really simple most of the time: if you're polite when you contact me, I'll explain anything you want to know or help you with quests or just about anything if I have the time. If you're a douchebag, you get to find out just how evil I'm motivated to be that day.
