Want to share a post from your blog on Facebook? If it's a Blogger site, that just got harder.
Facebook just added a Captcha check — a dialog box that asks you to type in hard-to-read text presented as a graphic — for any post shared from Blogger. Captcha tests are designed to filter out spam, since the bots that try to post spam links generally can't read the words (and sometimes humans have trouble, too).
