@Jefromi This new "mike kemsky" user is spewing misinformation and garbage across a lot of questions.... not sure there is anything that can be done, but perhaps it bears close watching. I already spent 5 rep down voting his answers.
I think voting is the right thing for now; he'll either calm down and only post real things, or see how his answers are being received and give up, in all likelihood.
@Jefromi Yeah, that Alaska one was one of the first things I read, but I didn't think it was clear enough to stand alone, so I kept looking. Plus, they have those scary giant cabbages.
@SAJ14SAJ Just remember not to go to his user page, visit all his answers, and downvote them all. The automatic serial downvoting algorithm will probably throw out your votes then.
@Jefromi You could migrate it to meta.SO, then you could put a bounty on it (assuming you have rep there)
@derobert I wouldn't do that. I downvote each answer on its individual terrible quality. Now, encouring you to go downvote them as your conscience dictates, that would be wrong :-)
