Please get in touch with @RedneffOxes to come to agreement. You either have to give him full authorisation to the account or you'll have to refund him the $15 he paid for the account. Failure to do so will result in a ban.
Doesn't matter, you are responsible for it since it is your IP. Unless you have evidence that one of your brothers did it. Also, since when does him not changing the password give you the right to scam him?
The IP in the email he received from steam matches with one of your IPs though.
I reposted the screenshot in a hidden post so staff members can still view it. Just to be sure, can you take another screenshot where the sender from the email is visible?
