You can buy Diggs and Stumbles (Digg and StumbleUpon votes) from uSocial and you can buy from 100 up to 1,000 votes.
I really don’t know who is behind uSocial (looks like SubvertAndProfit) but desperados can buy Diggs and Stumbles from it. Digg and Stumble packages start from minor league 100 votes to major league 1,000 votes. Check out how uSocial describes itself:
“…the world's best way to generate hundreds of thousands of unique visitors to your website -- quickly, easily and at a cost much less than pay-per-click or other advertising campaigns…”
Yes, uSocial is definitely for desperados alright but one thing makes me wonder. Buying and selling votes are wrong, they have different names but they’re very much similar with link-selling and link-buying but why search engines such as Google closes one eye on them?
