From the diagnostics page it looks like the server has a virus. You’d have to get the sysop to nuke it if it’s still there.

But first, try this: I found a suspicious bit of javascript at the bottom of the Rocket Queen’s sourcecodes. It’s so obfuscated it can only mean it’s evil. Try removing that before hunting for the virus.

Then google should automatically remove you from the greylist but you can also ask google to review your status if this goes on.

Good hunting!
