Along with problems with comments and unwanted CAPTCHA forms, we're seeing some reports about problems with persistent and unwanted interstitial displays, in Blogger Help Forum: Get Help with an Issue.
The interstitial display, and its use of cookies, is similar to the new mandatory anonymous comments CAPTCHA form. If your identity can't be determined, or your decision to view a blog can't be remembered, an interstitial warning is displayed - just as the CAPTCHA form is displayed, when your readers are preparing to comment.
