Detailed Description

Some functions to help implement an external link filter for spam control.

Todo:

implement the filter. Currently these are just some functions to help maintenance/cleanupSpam.php remove links to a single specified domain. The next thing is to implement functions for checking a given page against a big list of domains.

Another cool thing to do would be a web interface for fast spam removal.
