OP its certainly possible that they have only stopped your tips and not the withdrawals, probably to stop u from tipping to another account and withdrawing (i am assuming your withdraws are under heavy scrutiny)
regardless its certainly very bad look to treat one of their biggest players like this

You probably miss the part where OP explained that all of the balance was gone from his account. Don nicely quoted the image [I merged them both below to give a clearer context] to show that everything is indeed revoked.
If I may ask, what's the point of stopping the tipping feature [with an assumption that his withdrawal is not stopped] in concern of OP tipping to another account and withdrew from that other account? He can simply [suppose his balance returned] withdraw from his own account. After all [if we follow your assumption] it's not locked, he doesn't need to take a detour when he can take the direct course.
UPDATE
Account was unlocked today, but all my balances were reset to 0 before I was able to login (see screenshot below), so it's kind of pointless. [...]
