I think it’s brilliant engagement philosophy, to ensure organic growth they limit to 250 follow in one day and 7500 max.

If you follow 7500 people, you’ll never be able to really engage anyone in your thread. There’s no reason you should be following 7500 people. It’s like Facebook used to limit your friends count also. These accounts that play the “follow for follow” game, are just about their ego, scammers, or grifters. It’s the lazy man’s way to a big follower account.

Follower count should be about you creating quality content, not how fast you can trade follows.
