Hi, I run a Vanilla based forum (it's an open source forum like phpBB if you didn't know about it), today I checked at Google using site:example.com (where example.com is my domain) and I found results with descriptions like: Lots of them, obviously spam. I've reviewed my site and server and there are no traces of spammers or security holes but I upgraded my forum software to the latest version just in case. Any ideas about this?
I would check the source code and see if the text appears in the page, even if it is hidden text. A while back, there was a hacker that was adding hidden text to the descriptions on phpBB boards. A url might be helpful, as well...
Its also possible that someone has spamed your board,then you rmods has deleted the thread but while it was there Googlebot has spidered it
