It's a tossup between
Spoetnik,
MPOE-PR, and
mixan, but unfortunately neither one of them are active anymore. If I had to recommend the nicest member who's currently active, it would be myself. I'm not a cunt like OP and a lot of other shitposters and generally try to help people out even if they're being complete morons.
Or Jet Cash. He's pretty nice, too.
Edit:
TMAN used to be very nice, particularly to shitposting newbies.
Jesus, how could I have forgotten about him so quickly? Yet he's also inactive these days, so I guess OP's question has yet to be answered unless he goes for Jet Cash.
