Recently I found some service and softwares about twitter auto follow, however, some of them cann't be try-used. at last, i decided twollow.com and fastautofollow.com
Twollow is the maturer one, it is good in background service, and it can be try-used for 7 days. it is said that fastautofollow.com has a speed of 300%,and it can auto-unfollow , but it is a pity that there is no background service and it can try-used just for 5-days. it is unblievable that it is more powerful than others. who used fastautofollow.com,please talk about your view,thank you.
