I noticed a huge amount of spamming tonight. It's annoying, but, unfortunately, it happens, and our administrators have to spend all that time removing the posts and (hopefully) locking out those accounts.
That said, isn't there anything that can be done to prevent spam before it happens? On some other message boards I've been to over the years, new accounts have to wait a pre-determined period of time before they're allowed to post. This will discourage many spammers, since they want to get their "work" done as quickly as possible, not register, save the site address, and come back later to post all of their links.
