Are there any rules for being listed?

I typed in something to test the toolbar, and what I wanted didn't come up, but I clicked on an interesting link that put me in such a popup loop I had to shut down IE totally -- close one, the next came up, closed it, the first came up, closed it, the second came up, and it repeated and repeated and would not stop.

Sites like that simply should not be in any adult search engine type tool and should be banned from the industry.
