Forum account creation, spam filter

blinktag

May I object to the poor question used as a spambot filter on forum account creation?

"What U.S. coin is smaller than a quarter, but larger than a dime?"

... Well, monetarily (no possible answer), or physically (multiple possible answers)?

Maybe use a question with less ambiguity and only one answer?

(If I weren't a U.S. resident, I'd complain about the nationalism of it too.)
