Math Captcha for objects.reprap.org?

Reverting spam is No Fun At All(tm), and a boring and thankless task.

Any chance we could get some sort of captcha added for when you want to edit a page? I know that for a while wiki.laptop.org had a simple math captcha; you just had to do a quick equation like "64 + 5" and you could do your edits.

Any sort of control would do. The spamming process is inevitably automated and always easier for the spammers than it is for the cleaners :-/

Personally, I'd be in favour of locking down the object library for now. As no-one is contributing, this wouldn't be an issue. If people do have things to add, they can request an existing user/admin to give them an account. This would be a perfectly reasonably stopgap in the mean time.
