Spam out of control: Q&A ineffective

[Panzer Max]

You would think security Q & A would slow it down, but with the vB Q&A and a NoSpam! Q&A together, we still get 12~15 spammers a day who make it through the reg process. That's with StopForumSpam too.

If bots cannot solve Q&A, then there are people out there daily registering? Is that likely?

The vB Q&A goes something like this: What does a ship sail on? With the answers being waves, ocean, sea.

The NoSpam! question is more difficult:

To stop annoying spammers, we have to ask you a question. Yes, it's a pain, but if you want a forum free of Viagra and single-men adverts, help us out. Google is your friend. Please type in the name of the submarine commanded by Capt. George Street:

Come on, no one can answer that question without spending 30 seconds googling, you mean to tell me there are Philippinos in a warehouse somewhere actually going to that much effort to spam our forums?

Any suggestions would be greatly appreciated.
