Sorry buddy it's not my account. And I don't have multiple accounts. In this case, your account is an imposter. Such accounts are created for the purpose of deceiving users or scamming supposedly in the name of the person whose account name the scammer is copying. Such accounts, as a rule, are banned on our forum.
I nuke them when I see them.
Nuked.
Use Report to moderator button next time.
...I ban such accounts almost every day, if you see them, or if they PM you, report them ("Report to moderator" or "Report To Admin" if it's a PM).
