It probably fake followers so it's useless. I also have 2 twitter accounts with 50k each and 1 with almost 200k, all not affective as it is bot followers.
yes, the account should be viewed in detail about its followers, to check it out on twitteraudit, if the account has 98% real followers, then it's worth following bounty twiter, followers with 240k account but that free boot will get you eliminated from bounty the.
