I have been using both Addmefast and YouLikeHits for a while. It seems most people on BHW now prefers YouLikeHits but I do not understand this. These are the problems I found with YouLikeHits: Interface for perfoming action is awful. Too many people with massive amounts of YouLikeHits accounts give you high amounts of bad quality Twitter followers (like 5 simultaneous followers without picture, avatar and using serial names such as bot001, bot002, bot003, bot004). I always report these accounts as spam on Twitter. No country selection. Using Addmefast's country selection can mitigate the bad quality accounts problem. Using a language-targetted and excluding countries that are too unrelated to the target account is so useful. I found no way of doing this with YouLikeHits. So why so many people prefers YouLikeHits? Just because the volume of followers it has is higher even if they are too bad quality?
