Meet ShadyURL. It encodes URLs in things that look like spam, porn, malware, and cults/racism. Some of the things I've linked to various people in the last day:
http://5z8.info/killallimmigrants_x2l9n_protocols-of-the-elders-of-zion.doc (best URL so far)
And, just for fun, here's the Copyright Alliance blog: http://5z8.info/pirate-anything_w2x9e_racist-raps
And this blog: http://5z8.info/whitepower_o3q2x_inject_worm, which is awesome, because I'm actually 3/4 German
And yes, I have been made aware that I'm late to the party on this one.
