“Is this blog (which seems to deny the SARS-CoV-2 virus exists) protected against posting more than 85 words:”
No it was my choice. I do not like copying full stories.
Not a full story, but of providing more than 3 sentences by including what the FDA actually said, which is less than 100 words, and which is how many words are shown in excerpts on the list of articles. For those of us who skim the article page (set at 250 myself) then the 100 word excerpt (besides the title) can tell us if it is worth reading more of. And likewise the excerpt on the actual posted page (300 words normally allowed unless the article is small, and 100 for most protected sites, aside from the few "link only") helps save time if it includes the meat of the article.
Sorry to criticize you though, as that blog article is only about 500 words.
