Deleting X rated sites

[hal]

Hi guys,

Consider the fate of a manually edited directory. As people go out of business and lose their domain names, they are bought up by X-rates sites. On an edit pass just yesterday I dumped almost a dozen real estate sites which were found to now be X-rated fronts.

Does anyone know of a piece of software which a directory editor can use to automatically isolate and report on listings with questionable content?

Thanks,

Hal
