You know how when you open a BR window, you can see if the IP already has pending BRs?
Would it be possible to expand on that and either state how long ago the BR was requested, or at least whether the IP is currently timed out from posting?
I janitor a blue board, and the board has a lot of porn spammers. Sometimes these porn spammers wait out the BR timeout and resume spamming, and since there's a BR already up it can trick janitors into thinking they're already timed out and only delete the posts, allowing them to keep doing it.
