Sorry man, the downvotes are speaking for themselves (edit: the downvotes of political posts overall) and as you said, most political posts get downvoted. Just ignore them if you can. Poltical is hard to judge. The ones you're speaking about are obviously political, but there are many grey lines. I'm just trying to keep this community going and don't have the bandwidth or time to fight about what's political or not. I think you're handling it well, keep telling the people not to do it and downvote them. I understand why you're pissed, it's annoying, but I don't think this is the answer.
Edit 2: I'm working with return2ozma, hopefully they will comply and keep the posts to one a day.
Please everyone though, even if he only posts once a day, you can always ban just them. It's a no brainer and you have control of what you see. Any more posts that have voting without me agreeing will be removed.
