Spam in FAQ

somebody seems to have edited and spammed the FAQ page: http://www.tcbmi.com/strokeit/wiki/index.php?title=Help:FAQ

Someone has reverted the spam. But it remains a serious problem: I had already reverted similar spam a week earlier.

The wiki is great. But this spam is really bad. Today I reverted spam on the Bugs List, and 6 minutes later it was there again. See the list of recent changes:

Something ought to be done, such as blocking anonymous edits, or at least suspending their execution until reviewed by an administrator. Unless someone maintains this excellent wiki daily, it will continue to be a mess the way it works now.

I installed a captcha system for "spammy" page edits where an anonymous user add an external link to a page. Hopefully this will kill some of the bots without being too disruptive for normal users.

Ah, that is an excellent idea!
