Check it out for yourself, I've lost around 100 followers on a 15k+ follower account of what I thought were all real followers. After seeing that, I then went and checked my other accounts and lost 10's of thousands.. I didn't buy from the same people so I know it isn't just that, and it isn't just coincidence that it all happened at the same time. So I guess my warning is, if you have fake accounts, go log in them and tweet or something... because it's not looking good today. Sorry for the spam post, just thought I'd let you all know what I've seen and give you a heads up... I monitor Twitter a lot and this looks like a mass cleanup.
