Now his account actually was compromised because he posted that link. I locked it for now.
THANK YOU FOR CONFIRMING THIS. Didn't realize the account was taken over at the time.
It doesn't actually mean that you were talking to the hacker. The account might be compromised once he posted the screenshot, meaning he posted the thread and very possibly the hacker may not have posted anything with the account, but he certainly was able to change the password.
He got "user does not exist" same as I did may be because someone already did it before him.
