 Suggesting that, due to the complaints about trackbacks being used
 maliciously, that trackback validation become part of WordPress Core.

 Validation is a major difference between Trackbacks and Pingbacks in
 WordPress. WordPress should retrieve the page the trackback refers to and
 verify that it is in fact linking to what it says it is.

 While this is present in some third-party plugins, this would be a viable
 alternative for people who have completely abandoned trackbacks and all
 ping types in general due spam concerns to reenable the feature. Stopping
 SPAM in most cases is plugin territory, but this would reduce the
 desirability of trackback spam.

 Effectively, this would make pingbacks and trackbacks equally robust in
 WordPress, and allows support of the older standard.

 If the pingback verification code is separated out from pingback_ping,
 then it could be a function run by both.
