I keep receiving daily tons of POST requests from random IP addresses to wp-trackback.php. I believe this is the origin of my blank comment problem - http://wordpress.org/support/topic/42863
The requests have no referrer and no content and also have random user-agents.
Is there a way I can stop this? I need help, please.
A sample of the last POSTs I received, as logged by apache:
198.239.146.14 - - [22/Sep/2005:08:19:59 -0700] "POST /wp-trackback.php HTTP/1.1" 200 260 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030903 Firebird/0.6.1+"
207.87.58.194 - - [22/Sep/2005:08:33:23 -0700] "POST /wp-trackback.php HTTP/1.1" 200 259 "-" "Mozilla/4.79 [en] (Win98; U)"
200.177.112.145 - - [22/Sep/2005:08:34:21 -0700] "POST /wp-trackback.php HTTP/1.1" 200 261 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.1a) Gecko/20020611"
Do you have Bad behavior installed ? If not, it may help:

Try my fresh anti-trackback spam plugin:

Looking for testers anyway so please try it. It will certainly cure your problem.
TheMarco - having looked at your plugin though, what it does not do is stop the request being made. It will certainly stop the spam, but the reason I indicated Bad Behavior was that it stops the spam at the door so reducing server load as well as the spam.

Server overhead is really minimal with my plugin. It's in the same league as bad-behavious which performs some checks as well! In fact it runs more code than my plugin does. When a trackback request comes in, the very first thing my script does is check whether the key is valid. If not it sends a blank response and no WP code is executed anymore. I'm pretty sure this doesn't really differ in CPU usage from bad behaviour. I think it's even lighter.
Incidentally, I played around with bad behaviour and found that it lets plenty of spam through.
Bad Behavior lets a very small amount of spam through by design. This is because of my aversion to false positives. If you're seeing "plenty of spam," you probably forgot to activate the plugin. :)
A site getting 500 spams a day without Bad Behavior should see fewer than 10 a day with Bad Behavior on average. And I'm still working on it.
