Waitwaitwait...you mean that a service that makes it ridiculously easy to sign up for accounts and whose users judge relevance on total number of accounts "following" you has an extremely high rate of no-show accounts?
Also a huge % of accounts which are just bots. Some people / companies keep those bots as 'followers' to artificially inflate their follower count.
