I have also seen spam bots in Yanille advertising the new RS 3 Beta site. As far as I know there is no BETA runescape. I won't give the name of the site as I don't want to drive traffic to their site.
- The people who are advertising are normal players and not Jagex.
- I checked the WHOIS information and it is registered in Los Angeles and not to Jagex.
- If Jagex truly has a new version it would either be mentioned on the website or a secure email sent to players on the site and not advertised to everyone. The point of a beta is a controlled run to see how it works and get feedback from the players.
- The java certificate is not signed and therefore it is not Jagex!
I also reported it to Google safeweb as something that should be blacklisted. If it works and enough people report it then Google Chrome and Firefox (and maybe other browsers) will flag the site as unsafe and give those people who don't know any better a second chance before entering their log on credentials.
