they wont stop the captchas because they dont have anything else better to do,
why dont you try fixing some of the problems that arent posted, or you could spruce up the pages, or you could create more themes, there are thousands of things that you could do instead of placing a thousand captchas,

Hi Lisa, for anything related to account, password or sign in issues, we recommend contacting our Customer Care team at help.yahoo.com. They manage this and have the tools to help. We are going to close this thread since this forum is for feedback/bugs in the app/product itself. Thanks!
