function trackback_blackhole_init in Spam 5

Immediately drop all attempts to post or view trackbacks. The idea is to minimize the overhead associated with trackback spam attacks. With this module, anyone accessing /trackback/* will simply see a blank page, consuming minimal resources.

If you use the trackback module, then you do not want to also enable this module (tracbacks will silently stop working).
