I've submitted over 37K HITs on Mturk and have a 98.5% approval rate. I know one of my blocks came from NetMSi and the other from The Public Group (this being my 3rd block). I've read of some having success in getting the account unbanned; who can I contact? Does anyone have NetMSi's contact info as well (will try to get block reversed since they do seem to respond)? For some reason, I cannot fully check my dashboard to contact requesters. Help .
