I just received 25 boys from Veheme (we actually he over delivered) and they are exactly as described. They mix up the account names, have different bios and even put the first post.
I think this would be a great service for those looking to 'age' their 2.0's before actually adding any posts with links on them. Price is reasonable in my opinion. Sure you can 25 2.0 log ins on fiverr, but they don't have post, different account names, bios, pics and all that good stuff that keeps your 2.0's from being deleted. Well worth an extra few bucks if you ask me.
One idea for improvement is to monitor which 2.0s last. (I find OnSugar in particular to delete anything even remotely spun or fake looking).
Good luck with the BST!
