Contact support and ask for an account lock on the grounds of it causing personal harm. Or have a friend or someone close change the account password for them, then never tell them.what if the person selling have decided that eso is interfering with his irl and decides to wrap it up in a way he wont be able to come back?
That bold part is incorrect. Even after this the original owner will be able to prove they created the account as they have all the personal information and payment information.You actually don`t sell your account, you only sell the credentials, the account belongs to ZOS, it is in their database, they can do whatever they want with it, you only sell the login info.
And once fully "sold" the account cannot be reclaimed in any way, by fully sold i mean changing the E-mail address to the buyers E-mail and also once he changes the security question and answer as well it is impossible to perform a scam.
A lot of my PS4 firends bought accounts on PC, because they did not wanna grind to max CP all over again so i know from personal experience what it is the situation.
On the bad side, things like total noobs might buy max CP accounts and only light attack the content they meet, so there is that...
At this point they can just claim the account was hacked, give over the information and get the account back.
BUYING ACCOUNTS IS NOT SAFE. This can't be stated enough.
