Hello, I got transfer on my account, and I asked support and security about transfer policy at PokerStars. I sent few messages. And I had got few answers. I think, it's really funny, that ALL OF THEM are different :).
"Our transfer tool is only meant to help players fund their accounts
when they are unable to deposit with deposit options currently
available to them. All funds added to your account via transfer
must be used to play at our tables.
We are restricted by our license agreement in the Isle of Man and
this prevents us from being able offer a real money transfer
service for the purpose of cashing out.
You should use a money transferring service outside of PokerStars for
transfers which are not meant to be played at our tables.
We thank you for your cooperation and understanding.
Regards,
Colin
PokerStars Security Team"
