Here’s a very simple test you can perform at home if you suspect someone has bought their followers on Twitter.
Step one: Read your mark’s tweets. Go back a week or two if you can be arsed.
Step two: Ask yourself ‘would X thousand people REALLY be interested in that? Really?!?’
There is no step three.
PS – read Bill Rundle’s excellent blog post on follower buying for much more reasoned thinking than this.
Update: fakers.statuspeople.com can confirm any suspicions.
