Verification of comments.

I know Google, and others, are getting very security conscious but really this is now ridiculous. When I wish to reply to a comment you get a block of images and are asked to click on the ones that contain certain objects. I've just tried to clear this hurdle and after the 7th or 8th page gave up as it just kept saying 'click on these images' and giving me a new one. This started recently and I've got through up to now, though usually not at the first attempt. I hope somebody is reading this because it may be one reason why I get so few comments these days if the posters have to go through this rigmarole. Frustrated ? You bet.
