A good troll doesn't have a real home in the interwabs. There is no real home to sully like this. A troll has no ground to run to so they couldn't be smoked out like this. They are always moving forward to greener pastures and fresh hunting grounds. If one dried up like this they'd not shed a tear I suspect.

Then again, the 4chan folks would probably have too much fun if they got invaded en mass by the broody twilightards.

I've always been disappointed by the 4chan gags on XKCD. Imagine how lame it would be if he did LJ jokes on the comic?
