Why can't I follow/unfollow any more people?Right now, the overall following limit is 2000 and this is applied to all subscriptions.
You may also notice a restriction on the number of accounts you can follow and/or unfollow within a day. This means if you're planning a clean up of your followings then you'll need to space this out over a couple of days. We understand this may be a little bit of a pain, but have responded to our community's pleas to control manipulation of followings on accounts, as this behavior was deemed as 'spammy'.
If you do hit this limit please wait 24 hours for it to pass. As the limit is fairly lenient you should only be hitting it when performing irregular follow or unfollow behavior.
