I tried to use the "Contact Us" to report something to the webmaster, but after a few days I have not had a response.
Gmail has a feature where you can do: email@example.com and add something like firstname.lastname@example.org and receive email to your main inbox.
I recently started receiving email regarding Legal action for my non-existent Runescape account to the email address that is only attached to my MMO-Champ account. It even has the same (deliberate) typo in it, so I know it wasn't guessed.
Either you have/had a breach or you have shared my email address with a phishing group.
I expect a response.
