How old is your account? I have one from 2012 and I follow around 1k a day and unfollow 5k at a time sometimesI cant vouch for that site. I personally use Tweepi.
It's pretty much the same you can follow, unfollow users that dont follow back and so on.
+1 for Tweepi
EDIT: I follow 600 everyday, when my following ratio is crazy compared to my followers i wait 3 days then unfollow users that dont follow me back.
