Why should i be responsible for some noob?
Yes, I think you are not responsible for that and you should not be responsible for that.
And btw who can prove he is scamming?
S/he is selling account which can increase scam, spam. And once s/he will sell the account and the account will be tagged and after tagging the account will the seller return the money? The seller knows very well that account will be tagged that's why not posting from the real account or s/he has no legendary account.
