In here is gonna be the list where you sell an account you are able to change either the pass, email or both without getting banned
post here some trackers that you know what you can do either or or both, also included are workarounds

"I suggest to all the traders, to change the emails in their accounts NOW. (if the registered emails are connected with other trackers/forums etc)
Each account must have a different email and a different username than the other accounts. Don't wait to change it when you decide to trade the account. It's too risky to change the email and trade the account after 5 minutes... And of course it's even more risky to trade the account and the new owner to change the email !!! It's safer to change the email NOW and to continue using the account from the same IP for a while. If you ever decide to trade/sell it in the future, you are taking a smaller risk. But don't forget that trading accounts is always dangerous, so discuss with the other trader/seller the possibility the account to get banned." - thetrader
