We apologize if this is an inconvenience to users who try to sell their accounts, and we have done our best to cater to everyone's wishes. However it has caused more frustration than it's worth for everybody.
This is also a reminder to make sure your PB Mining password is different than your e-mail password. For someone to change the payout address under your account, they would need access to both your PB Mining account AND your e-mail address. For this reason, the passwords should be completely different. You can change your password under "Your Profile" settings.
This is not right. The users who purchased until now have done that knowingly that they could change their email address. You can't jut force this upon a 5 year contract that was bought under different terms. Maybe someone has a payd email service and doesn't want to renew it, or has it's address on his own domain and he doesn't wish to prolonge it no more. There are more reasons beside selling the account. It's wrong to change the terms on a contract that someone has no way out of it.
We will manage it on a case by case basis. A user will have to provide valid reasons and possibly further verification before the change would be made. Also, the option to change the e-mail address was never an option in the first place. People have always made special requests for it, about half of them being attacks on hacked e-mail accounts.
