Honestly, it has nothing to do with that. Transfers are temporarily unavailable. There was a 'secondary market' for our promotional servers. The problem is that we were getting tens of requests per day after Black Friday, and it puts huge stress on the support queue - add to that the fact that the new user might try to hold us responsible if the seller misrepresented something to them.
We will bring transfers back in a while. As you said, it is in our long term interest that people use their services and renew them and allowing transfers is a good way of ensuring that.
