Interesting. They post a lot of crap stories around. What I want to know is how did you audit their twitter profile? When I tried to see what mine would be like it said I need to sign into my own account.
I think you have to sign in to your account and then it can audit other accounts. I logged in as mine and then audited a different one.
It isn't perfect because one I checked (who I know) has less than 10 followers and all are real, but it says 1 is fake. It is all based on statistics so isn't perfect, particularly with small samples, but I guess should give a reasonable idea.
