New Captcha for the forum?

[sjau]

Hiya Falko and Tim

Howabout using the same Captcha functions that you use when creating content or adding a comment to a howto for the forum here?

I just noticed there's been quite a bit of spam focussing here.

I'am not sure if the spam is submittetd by scripts bots or "human bots"...

There is a captcha when you register a user in the forum and unregistered users are not able to post.

There are plenty of methods to circumvent captchas. In the okopipi blog there were a few ways on how to do it and I just think the one of the drupal is a lot harder to crack then the one of vB...
Another possible thing as captcha would be like a question: What is the capital of India... or how many states does the US have or the Marseilleise is the national hymn of what country or or or....

Add-On: This guy here has decoded a lot of captched - e.g. vBulletin - but not yet Drupal http://sam.zoy.org/pwntcha/

Maybe give some more known users the option to delete "spam" ?
