We've had an increasing problem of spammers trying to sneak spam onto the forums by putting up posts that consist of material copy/pasted from elsewhere on the forums. Later on, presumably after the post has passed initial inspection and is no longer on the moderators' "new post" list, they edit in spam links.

Late last week we adopted the approach that (as mentioned by pvonk) many other forums use to cut down on this kind of thing. You can still edit posts, but only for five minutes after it goes up. Then it's frozen.
