So, as a follow-up in my support ticket I got this reply:

Now here's the thing.. I re-read through their whole TOS and I am still within the rules.. however I've noticed something weird.
My list of deposits through Bitcoin sums up at $1165.87, and my withdrawals to $1115.86. The difference is $50.01 just like my typical method of redepositing and withdrawing has always been.
In the withdrawal page I get the message saying that I can only withdraw $12.81 to my Bitcoin account.
Subtracting that from 50.01 leaves $37.20 behind which is the exact amount I have always been redepositing again and again.
So, there must be something wrong with one of my deposits, and looking at the list I notice that one of my deposits shows my email in the Account column while all the rest show my username.
Their TOS has this rule that might have been recently added:
Quote:For security reason, payment processor's email addresses used for withdrawal must be the same as payment processor's email addresses used for deposit.
So this may be the actual root of my issue. I still don't understand how it happened as I've always withdrawn and redeposited using the same account.
It's ridiculous how many times history has always been like that, beating me up at the exact point of the change in my start-to-make profit point of the curve on so many programs..

At the worst case scenario I will have to make a pure deposit of $37.2 + $29.09 just to unlock everything..
