I have read about the rules. One of the rule/policy of Twitter is " In addition, every account can follow 5000 accounts total. Once you’ve followed 5000 accounts, there are limits to the number of additional accounts you can follow: this limit is different for every account and is based on your ratio of followers to following."(https://help.twitter.com/en/rules-and-policies/twitter-following-rules)
Actually, I want to know the exact ratio. Suppose I have 100 followers and 500 following, so my follower to the following ratio is 1:5, then how many additional people I can follow? Is there any formula/algorithm behind this? I think Twitter does not clearly mention the formula, that would be a great help.
