Virgin media (maybe others) have suddenly dropped another layer of security when logging on. "I am not a robot" link takes me to 12 small photos of various items some of which you cant make out what they are. You are then asked to tick all which have a certain trait e.g. all with salad, or all with water, or all which have fish> If you get it right you then have to confirm your log in details again. If you get it wrong you have to try again.

I find them much better than the captcha letter systems. Captcha were getting harder and harder as the recognition systems of spambots were improving but were also becoming illegible to humans as well.

Yes captcha was is a pain. Would have to refresh the letters several times before I could decipher them.
