I bought a Fortnite account on the internet. Everything went smoothly. But today I played on it normally and then I got one in the group gejoint and said that the Acc is someone else. I have access to the Acc, which means that I can change that password, which I've done twice. What should I do now?
Nothing, if he reports you, just banned
Not necessarily he can prove that it is his and this was taken from the must be reassigned to him
He has an account sold that one may not so this account is blocked as a penalty. There's nothing more to say.
Not necessarily can be proven that the acc was stolen he is legally still his and this is entitled to claim that is the legal situation that applies also to fortniete and yes that it is intent
Well, because you have obviously bought a stolen account.
The sale of accounts is prohibited and will be punished accordingly with a ban. That's just the risk with illegally acquired accounts (you do not believe that people sell their own accounts in this way, right?).
The result will probably be that he reports his account as hacked to real owners, this is blocked and he gets it back.
Since you have nothing to prove that it is your account (except a confirmation of your Hehler), you have nothing that gives you any right to the account.
What should I do now?
Learn from it and in the future only buy from official dealers.
Nothing, the worst thing that can happen is that you get banned because selling / buying an account is prohibited. You should always expect something like that.
If the account was stolen and sold, it will be blocked or returned to the original owner.
If the account was sold by the owner, it will be blocked and will be locked because the sale of accounts is prohibited.
The FS will not be able to prove that it was originally his account because he will not have all the data the creator of the account has. Latest at the key or proof of purchase is over. Not to mention the IP address that was logged in before the account was purchased. That does not belong to the FS.
