=================================================
Trakbacks on PEARWeb and PEAR::Services_Trackback
=================================================

:Description:
    I finally found some time and improved the trackback handling on PEARWeb:

I finally found some time and improved the trackback handling on `PEARWeb`__:

.. __: http://pear.php.net

- HTML entities in trackbacks are now decoded before using the bad-word-filter
  (this will go into `Services_Trackback`__, soon) and I updated it with
  common bad words. 
- Only 3 trackbacks per 30 minutes will be accepted from a host from now.
- If both of these criteria do not match, it uses DNSBL and SURBL mechanisms
  to check trackbacks additionally.

Only trackbacks that come through these filters will be added to PEARWeb (and
still need manual approval by package maintainers). Compared to the past we
now receive only 10% of the spam, I estimate.

.. __: http://pear.php.net/package/Services_Trackback

Unapproved trackbacks will be deleted from PEARWeb automatically now, after 14
days, so maintainers who don't care about trackbacks can simply ignore them.
At least, a lot of maintainers seem to care about trackbacks: By now we have
more than 250 valid ones, which enhance the packages documentation with
additional release information, use cases, examples and hints. I think this is
a valid point for having trackbacks for our packages.

Any further ideas how to fight trackback spam?

  "Any further ideas how to fight trackback spam?"

  How about integration with Akismet?

  Sounds like a neat idea. I will check that stuff and propably write a spam
  plugin for Services_Trackback for it. :)

  Thanks for the hint! Toby
