Oh, I see it a lot with low level night elves. But I've seen a bunch more Gnome griefers as a percentage of their playerbase than I've seen Nelfs, because half the griefers I'd see were gnomes. Given that gnomes make up only about 10% of the alliance playerbase, that shows that at least on some servers, gnomes DO grief more often. When I played alliance, I'd rarely see high-level non-gnome players ask for free **** at max level, but I'd see a 60/70 gnome sit in IF spamming General endlessly asking for free ports, food, and stuff all the time. When it wasn't a Gnome, I will say it was usually a NElf. Given my convos with other ex-Alliance, I'd have to say this is not server-specific, though
If you're on a PvE server of some sort, that may influence things, though, as gnome players seem to be something like UD are for horde: the race you play because it's good in pvp, not necessarily because you like the race.
