create a bunch of accounts.. go into something like r/karma4u or whatever and get a bunch of accounts up in points all for the purpose of sticking it to them.

the leftists on reddit are so whiny 'waa you say something i dont like, i ignore reddit rules and down vote you.. then i go to my other account to down vote you to get to -5 so no one can see you'

it's the worst way to run a site, and encourages censorship.
