stevegee58 writes "A tumblr blog entitled 'HelloThereRacists' is publicly identifying other online posters who make racist/assassination comments about President Obama. Beyond merely identifying online usernames, the blog's author is uncovering and publishing the real names and locations of offending posters. It's an interesting mess of legal issues. The outed posters are at risk of a Secret Service visit, but the trouble may not end there. The HelloThereRacists blogger himself may have some problems publicly identifying posters, who are frequently underage teenagers." Update: 11/16 19:17 GMT by S : The blog has already been taken down.
