Google's Blogger use to have word verification for the posts. When you create / edit a post, the word verification has to be done before publishing the changes. Though it prevents the spamming of the system, some times it is cumbersome to understand the words shown for the verification.
Apart from the sheer lengthy words, the display use to be convoluted which increases the frustration. Off late, I see blogger has removed word verification and does auto save as draft. Way to go!
Finally, I figured out that word verification gets shown for a blog that gets classified in spam category (because of the high number of posts). However my blog turned out to be false positive. Over a period of time (and some tune up to the algorithm), gave a clean chit to my blog . Hence no more word verification.
