.  I recently posted about YouLikeHits bit.ly/qZvNWp as I have used it for a long time and really like it - however there have recently been a lot of fake/spam accounts using it with the result that if you exchange your daily credits for followers most of those credits are being wasted by these useless followers. I still find the site very useful only at the moment I'm tending to exchange my credits for retweets instead of followers...
