so you follow and unfollow, blacklist those you unfollowed so you dont follow them again. now, i suspect for that to work (not following unfollowed users), the following and unfollowing have to be in the same project. when FL finds a person to follow, it checks the blacklist first. if the blacklist is in a different project, it won't see them, and hence it does not work. for the same reason, if the blacklist is deleted, FL will follow people that you have unfollowed. However, if you dont delete the list and when it gets very long, it will freeze up FL because it takes effort to load the list. (I wonder why nobody has this problem?) i do not see (or know) where else FL save these lists other than on the fly?
