Back when I first started playing and fall damage would kill you, I would be that guy offering tp's across steel canyon except I would just drop lowbies off of the highest building. I realize how horrible it was but since it happened to me countless times I didn't really care all that much
. Lots of people got a kick out of it and after a good laugh I'd take them just about anywhere, however some people really got upset and would freak out in team chat, not realizing I could tp them straight from the hospital and kill them again. Usually after that they would quit the team and start the broadcast hate which I didn't mind either. I know it was horrible to do but in reality it's not that bad...
The other thing was back when Perez park was pretty much mandatory And there was no aggro cap I'd fly around gathering as many mobs I could and then drag them to a lowbie and watch the "@_@" appear in chat as a massive wave of enemies would run them over. Once again happened to me many times and was another "for teh lulz" moments when you were bored. I did however do this when there were three full lowbie teams of 8, they actually got through the gauntlet of death.
Despite all the early years of trolling I think my karma finally balanced after the AE/mailing system was released. I had an elec/fire brute IO'd out for defense, which sounds dumb but I could do max runs with a full team of 8 and only spent about 200mil on the thing. I would gladly take along anyone who asked instead of charging out the you know what for a couple runs. I would also mail 50+mil sometimes to random people I seen just to see what would happen. Even more often I would give the people at costume contests who didn't win but had great concepts free inf, usually more than the actual winners.
I think my dumbest move would have to be trying to organize a villain side hami raid at random... 4 hours of stressful organization all for nothing... But would I do it again after losing this game, he'll yeah.
