Does yahoo think the captcha chat thing serves any real purpose?:?

Those stupid codes you have to type in only annoy the real users - there are as many bots in the room as there always were. The people behind the bots (who have to type in the codes) are being paid for their time and trouble while us poor schmucks have to labor to read the code so we can type it in and then enter a chat room filled with bots. Wish yahoo would realize the whole captcha thing just wastes our time and gets on our nerves.
