Same problem, account locked after 2FA googleauth setup, OTPs just didn't worked during my next login. Looks like they have 3 different QR codes for login, transfers and withdrawals, I scaned all 3 QRs through my GoogleAuth app, but just 1 line was added in GoogleAuth app for TradeSatoshi and as I said before I locked my account trying to login. I have submited a request from the site, but still no any respond.
solved
