Assume you have a user content site - or you're using software that can somehow get spam links inserted into it.
How do you find out if your website has spam put on it?
It seems a common enough problem these days... people putting spam links on websites. Surely there must be a service or piece of software to detect such a thing?
I can think of a few ways to go about writing one fairly easily (using existing spam detection tools... but applying them to a spiders crawl of your website). It would be much nicer if there's already a tool which does such a thing though.
