Stopping Spammers - Q&A Needed

[Arcada]

Too many spammers are getting around the ReCaptcha security in member registrations, so I think it's time to change things around a little...

One of the most successful methods of human verification is an easy Question and Answer. The answer shouldn't be one that is easily Googled (by easily I mean by bots, not humans) and preferably unique to this site, so for example :-

Q) Which in the following list is NOT part of a Pedal Steel Guitar? Leg|String|Lever|Screen|Neck

Was one I came up with quickly just to get it implemented. But as I don't know much about the subject, feel free to reply here with your own suggestion(s). The more questions there are, the better.

Don't make it too hard - genuine potential members, i.e. anyone with even a passing interest in Steel Guitar, should be able to answer it correctly.

Also, questions can have more than one correct answer, if need be.

One quick point - I'll remove any Q&As from this thread when (if) I use them in the actual registration process, as leaving them visible here would be counter-productive - a list of all the questions and their answers would be a bit silly to leave up, after all!

It's early days, but since implementing the Q&A challenge more than 24 hours ago, there have been zero spam signups.

For it to keep working, we need some more questions, though....

Thanks, that's exactly the kind of thing I'm after (although maybe a little hard as I'm not 100% sure myself).

Keep them coming

P.S. Please post (or bold) the correct answers as well - I do websites, not PSG .

Thanks again but remember, I need the answers, guys! I'll delete them from here once I've taken them...

Also, my fault for not specifying but questions should be either multiple choice or in the format: -

"Grass is to lawn as _____ is to forest" (A - tree)

leaving no room for ambiguity...or if there are mulitple possible correct answers give me them all

[Arcada]

I've removed all submitted Q&As from this thread and taken note of them - thanks again.

Keep them coming, though...since implementing this almost two weeks ago there hasn't been a single spam signup so it obviously works, but to continue working the question "pool" has to be updated on a regular basis.

Good work, I have noticed the difference in the last fortnight & have only just seen this thread
