On dekaron everything can be taken back. How? Easy. The registered email can be taken back by contacting the email provider. Let's say.. Yahoo. You call the yahoo support, tell them your account has been hacked and they will ask you for some private infos. For example the date when you created the email, contacts you've sent emails too, etc. Once you answer the questions, you get the email back. With the registered email once taken, all you have to do is send a ticket to nexon and ask them to re-send you the account infos to the registered email (I did that like 1 month ago when I reinstalled windows and lost an account). Account buying is really not safe and I wouldn't recommend it.
