Are there any "custom question" spam modules available for G2?

Hi,

Is there simple "custom question" comment spam prevention module available for Gallery2? I mean the kind of module which asks things like "What is the colour of Pink Panther?" or "Are the pyramids in Egypt or in Sweden?" and visitor has to put the right answer to the box before he can comment something. I'm building a websites for couple of clients and I found similar plugins for forum software and also for blog software but for Gallery2 I couldn't find it. For Coppermine Gallery it exists but I wouldn't want to change the gallery at this point.

It would be nice to have similar spam blocking system in all. I have right now reCapthca in Gallery2 and it seems to be very good but it's very different from those other spam plugins and I can imagine that it just raises question from my clients like "why this can't work like the others?". I wouldn't want to explain it to everyone.

Thanks for the info.
