It sounds to me you did some manual (and pretty crippling) hack to disable links sent in forms. If so, it's something personal you've done and has nothing to do with the official code of Geeklog and Spam-X, which I've asked about.
Unless you just meant you manually add bad links to Spam-X, which is a pretty Sisyphean task if you ask me.
You keep saying if only I didn't change stuff...but I didn't change anything in Spam-X. If you have the beta version and not what I stated above, that's a whole different story.
I've been getting these as well.
So far as I can see, Spam-X does not block plain-text URLs written in an e-mail message. I tested this by sending myself e-mail through my user page that said "hello! http://www.evilmadscientist.com/" (my own URL!), and it got to me just fine.
So... I imagine that there's no good way to stop this type of e-mail, short of deleting all e-mail that contains a URL, which is not something that I want to do in general.
Thanks, Dirk! See, Ironmax? You could have saved a lot of writing...
