Okay, this place seems as good as any... as many will notice, at the best of times and certainly at the worst (like the past three days, when I've been travelling and/or sick as a dog) the spam isn't cleared up as often as anyone would like.
Unfortunately there's nothing I'm aware of that solves this problem preemptively; these are real people fully expecting to get their posts and accounts deleted, and it's still worth it for them. No tricks or verification steps we can put in the way would change the fact that they are able to proceed through them as well as any of you.
Please nominate moderators here. We'll be looking at three or four. Feel free to nominate yourself, but we will only be taking people we recognise (with a history on the forums, who isn't likely to disappear soon, etc.).
I nominate luna.
