Occasionally, depends what you mean. Only 70s, I don't waste time going into noobie zones. I'm generally in (1) arena, (2) a raid, (3) dueling outside org or (4) doing dailies somewhere.
Sometimes I do dailies in peace with other Alliance around. Other times I just see a perfect shatter oppurtunity and try and 2 shot the person. Sometimes random PVP keeps me from getting ridiculously bored.
I like to kill people who will at least fight back, so that means people who visibly have lots of PVP gear. But I don't limit my kills to those people of course, sometimes I just want to see big crits and the 0 resilience players are most fun for that ;)
To be fair I do dailies on my PVE gear. Higher crits, higher damage, but higher chance for you to kill me. Heck I don't even quest with a PVP trinket on anymore. If you wanna fight back you probably have a good shot, I just like random PVP.
Maybe once every few months I'll take a run through newb territory for lols and just kill people. Usually I'm there for an alternate reason (helping a friend) and I just kill reds along the way.
Once in a while though, I take my rogue to Org or SW and gank in the city. In fact maybe I'll go do that now, I'm pretty bored and it's been a while. I like the lol's generated by the other faction, everyone loves finding an enemy deep in the heart of their main city.
