Account is 1 year 8 months old. Has 20K following and 27K followers. I am not using any automated tools. All of it is done manually. I was originally following/unfollowing 200/day until I got to around 20K, then I moved it up to following 400-500 (max) per day - sometimes I won't even reach that many in a day. And/or unfollow around 380 per day. Account was locked twice in a week without any change in my following habits; I was doing the above numbers since late September 2016. One of those times, I was at 0 following for a while, and I lost almost 2k followers because of it. I always believed that aged accounts or larger accounts could follow or unfollow more people in a day without being suspended, or even locked for that matter. So what are safe numbers to follow or unfollow per day with a 25K+ account?
