Here is a compilation I did a while back of the worst of the offenders
http://www.planetmule.com/forum?topic=1189.msg6230#msg6230Seems like I'm always going back and adding to the list of post about him.
A few others to watch for...
NilacTheGrim
SockMonkey
a few others I can't remember right now, these are the infamous ones.
You'll notice a lot of complaints that in the end don't raise enough concern for me not to play them...
Everyone gets tagged eventually. A few regulars here just have an off day and go to war on each other and decide they won't play each other anymore, but even they are all right most the time.
You'll notice Death_Mule17, aka MuleSizeMe feuding with Whoosthis, aka CDay. For the most part they are both ok, maybe one of them is a little bi-polar or something and has a few off days. I play them both, usually have good games with them.
The following are people I know are usually decent.

Many More, but these are the people I know I see a lot of and have played and believe to be generally cool.
I personally have not had a bad experience with Death_Mule17 or WhoosThis. They are currently feuding, but hey whatever. ZX81 likes to start games and then when people join he isn't always there, and so you'll notice they'll all leave and find another guy to be player four in a different game, but when he isn't AFK for to long, he'll give you a good game. Just keeps you waiting to start sometimes. I wouldn't say that is all his fault, we are all wanting Admin to change the chat system to it's easier to know when people are waiting to play (the alert system in Planet M.U.L.E. currently sucks)
It's usually easy to spot the really bad players in the forum, the problem is, most noobs don't look at the forum. There are usually multiple complaints about the serious problem makers. If everyplayer stopped in at the Website, Scores Forum before they played their first game, I'm sure we'd have fewer bad experiences.
