Yeah, I can see the vote bot problem is a bit out of hand, but there's not much you can do about it currently. I've cut back a lot on using them because I don't really agree with most of them. The only one I've been using still is minnowbooster, and that's only in hopes to help promote my posts and maybe grab a few peoples attention so I can find some loyal followers who enjoy what I post. I think just accepting it and focusing on rewarding content which you enjoy is the best thing to do, man.
