Description:
To either slow down human abusers or weed out bots, please allow AbuseFilter to present a CAPTCHA & allow the change only if solved. Yes, I'm aware that captchas are mean to humans both blind and sighted (though of course a particular horror from an accessibility standpoint) - they'd have to be used sparingly etc, but that's a useful option IMO.
