Would it be possible to add spam blocked & flagged (and maybe other internal) stats to the super-secret-ana______-page?
This probably would fit the description of "low priority" pretty well, though. It came up in TL earlier as a curiosity, and it's still pretty much just a curiosity, but it's one I'd really like to see implemented.
By which I mean: the mod tools are designed to help us see our site health. Spammers would logically only attack a site they think will have views, so knowing how much spam we get gives us deep, valuable insight into how our site is doing. (Dear gods, that was supposed to be sarcastic but actually made a little bit of sense somehow.)
