I actually switched back to DTSM now...
The pool shows me the same hashrate, so this guy is either lying about the hashrate or he is taking more dev fee than he says he does.
Either way pretty scammy.
Plus, he can't even get e-mail adresses working properly.
I have asked >10 users to try out the feature of putting email into the username and all of them report it is working perfectly. Can you double check your command line?
