It would be extremely useful to have a log of every time the spam blacklist blocks
an edit, with the URL that was blocked.
This would pin down problems on all the different wikis with filters that are too
This would also tell us whether our filters are actively blocking spam, and how
often different spams are attempted, and where.
This would also help us know when to expire filters from the spam blacklist (say,
after six months or a year of inactivity).
