We have to do it, because Verizon Media (the company that owns Yahoo) decided to see if it would be effective in reducing or eliminating spam bot posting. I've noticed on days when I need go through few captchas, chances are high I'll see some Yahoo Helpline bots on the Yahoo Products category. On days that I have to go through captcha more frequently, I don't see those Helpline bots posting.
