Unfortunately, "awareness" does very little, and the GMs are very bad at dealing with these situations. The most effective means of stopping these scams is to report them directly to the host of the website in question, as well as use some scripting to spam their website with fake logins.

If you'd like to do more to stop these scams, you can report them to the Anti-Phishing Guild when you get these tell messages.
