Hi!
In November Marc Perkel announcend a trial of a DNS based list of short
URL providers. At the time I mentioned that I planned to add support for
that list in my URLRedirect plugin.
That support is there, and it seems to be working.
This module follows URLs (in parallel, using HEAD requests) matching
specifications or found in a DNSL and adds the location of redirections
to metadata (so that the "real" sites are checked by URIBLs and other
rules). The addition of Marc's DNSL might make the plugin a lot better,
since I did not have an updated list of URL shorteners for it.
The module should be seen as a test of concept. If spammers abuse URL
redirectors this module and Marc's DNSL could help, but I have not
collected any stats to see how helpful it is in practice, and I don't
know wether Marc's list contains the URL shortener services most abused
by spammers.
Regards
/Jonas
