Tatyana and Clark
Those that have been banned are those who have blatantly and consistently tried to push extreme views quoting many suspicious websites and being pan-conspiracy theory advocates. Paul was a vehement anti-vacxer. There are still some covid deniers and skeptics who still freely comment, I could name one or two. So the ban is not total.
Each website has its rules and of course the website owner has a legal duty also as we know from Craig’s trial that commenters’ comments may also break the law potentially.
