The biggest douche move, by far, was people who stole SG's (and more importantly all the items in storage), this didn't happen to me, but it occurred often enough. Groups of people lost months of effort in a blnk of an eye. All for some sweet sweet, loot!
Personally, I ran with a group of people, some of who were badgers, some who weren't. Us non-badgers got particular delight in getting the difficult "Master of...." badges and setting them immediately as our title badge. Then we would parade around in high traffic areas like RWZ, Hami raids, Pocket D to show them off to all the other badgers on the server. "Oh this? Well, here, if you like that one you'll love this one!"
