MMOGA account?

Moin, I got an account from a colleague who bought an MMOGA Fortnite account for 1.80 euro. Although the new season has only just begun, it is already at a high level, which suggests that he was still playing on it today, because The whole thing came across as very strange to me, I joined a few of his friends and asked if the owner of the account had even sold the account or if it was hacked. Now I can't get into the account he bought because the data was changed, which I don't think is bad because it is his account that may have been hacked for which he can't do anything.

Can you tell me what that means?

If you buy accounts then right… Where all the data is included, i.e. Email access, etc.

without email access you can be sure that the account will be gone after a short time…
