I think the combination of simple arithmetic problems and the locking
of the main page has helped to block spam (maybe spammers give up
after failing to mess up the main page?).

It's been pretty effective.  In the past we had to revert spam at
least twice a day.  Now it's been quite rare.

Best wishes,
