I heard through a couple of different sources that it was difficult to post comments on this blog.
One of those would-be-commentors went the extra two miles.
He determined that he needed to change the settings on his browser to allow third-party cookies and tracking. Blogspot is a Google/Alphabet company and they are undoubtedly attempting to make the enterprise show a profit via advertising and data collection revenue.
If you are concerned about privacy issues and are compelled to comment, I suppose you can scrub your history with a product like CCleaner, enable cookies, post the comment, dis-enable the cookies and then rescrub the memory.
That won't protect you from NSA, the Russians, China, keyboard trackers or bedbugs.
However, I am not a computer experts. YMMV
