I've just reviewed the brandon6.0 account, and there definitely seems to be some suspicious activity. I also see that the e-mail address on this account was changed on 3-15-17, after which several items were immediately listed for sale.
Can you please confirm the previous e-mail associated with the username, prior to the account being hijacked? That would prove your ownership of the username, after which I could change the e-mail to something new of your choosing and then you could reset the password via the lost/forgotten password link. Feel free to PM me the original e-mail as well as the new e-mail you'd like to change the username to (this must be an address not currently tied to any other username.)
