Tip for earning Giantbomb quest xp fast

start a thread that has a provoking subject (usually involving one of the staff members). Then, after you get several dozens of views add a slightly offensive (but not racist or sexist) comment that makes suckers follow you on GB.  
 
You're guaranteed to complete several quests (or stages within a quest) and circa 1000xp before the mods lock the thread.

OR you could not be a dick. That would be the smart thing to do.
