Hai Guise.. So recently twitter has changed their limits on "safe following". I had two acounts suspended for following & unfollowing about 400/day with 10-30 second delays. My third acc was doing 250 follow/unfollow a day with same delays and was safe from the ban wave. Post your strategies and follow/unfollow amounts here. I've also read on these forums that the safe amount you follow and unfollow depends on your follower count.
