Yes you can use it in your next release.

I did think about the non wordpress sites, but. I didnt find any large blogging system that auctually have a trackback funtion in place. When i do, i will update the code to allow that system too.

Plugin updated and i think i got a good way of stopping trackback spam, without turning it OFF or using something maybe not all users do not have access to.

The upadted checks if the blog that is sending the trackback is an auctually WordPress blog. If it is, then it will allow the trackback. If not… die();

i have seen a few use the trackback, that is the reason i dont want to block the function.

I have not been able to find out if other systems can post trackbacks, or its only WP. Yet. Still looking ??

Togeather with my idea partner i might have found a way to identify spam trackbacks without it ever can be a false positive.

Just need to figure out if its possible to post real trackbacks from NON wordpress blog.
If it is possible, then this idea cannot be used ??

Anyone know if it is…
I know you can do a custom POST, but does any systems provide the trackback funtion?

Thank you for the good examples, me and the other coders will see if we can figure out a simple way to block this and still allowe real trackbacks.

The urls that do not exists, could be one way to remove some of it. By checking the URL of the trackback.
