Thanks for writing in for further clarification. To clear up any confusion you did not hit a limit for following too many accounts, but instead for re-following the same accounts.
Our Trust & Safety team has implemented a limit in response to the community's request to curb behavior where an account follows, unfollows and then re-follows the same account(s) again in a short period of time in order to unfairly boost their own followings.
If you were not aware that this was happening when following people from your account, do let us know. The next time it happens get in touch with us and we can investigate further.
Based on this feedback from our users, who said it was causing annoyance and confusion, we have put limits in place to restrict this behavior. Your account has been blocked from following and unfollowing for this reason. As we wish to prevent this activity in the future, if you run in to this limit repeatedly, each block you receive will increase in length.
These limits are in place to address community complaints about accounts overusing, or using features in a way other than as they were intended. We hope you can appreciate why we felt it necessary to put these limits in place.
