as a person who deals with spam daily, it's only going to get worse. I can also say it can get a lot worse really fucking quickly. I'm guessing that the easiest implementation to deal with the issue is that on submit of the registration button, it fires an email off to the mail list, where we can all see it, and then an admin (in all honesty, other than malreaux, I've no idea of who they may be) can allow the registration to finish or dump it after taking a look at the form contents.
I'm sure Mr. Anderson will have a better handle on how to get it sorted with a minimum of fuss and bother on his part (or at least, he will after he gets back from Rivendell), but it is something we need to deal with, and the sooner the better.
It would really suck to come in and find hundreds of postings all over the fucking place one day.
Oh, and as an aside... wtf guys, leave the political animosity where it belongs... politics and flame. I get worked up with the best of them, but it's not like I don't view all of you with a great deal of affection and respect. It might be a good idea to remember that. Leave that shit out of the Suggestions forum mkay? I go there for the proto-twitter experience, not to watch a couple of prima donnas squabble over format.
