If your main "runescape.com" is reported, make a subdomain to see if that'd be frauded as well. Other than that, Make folder like runescape.com/m=weblogin/c=asdasdjnasjod/index.html
Are there no other solutions to this other than changing the subdomain? I have run into this problem multiple times in the past few days and its getting frustrating changing the subdomain every day.
