Yesterday after several posts in the Coronovirus thread I got a pop-up telling me that as a new user I had reached my limit of posts allowed in a thread (I signed up here over 2 years ago). I emailed admin to point it out, but no response. Today the same thing, only as a new user I had apparently used up the three posts allowed in one post.
I really hope this is a glitch, not underhand Stasi-esque shadow banning. While I disagreed with some on the Coronovirus thread, I did not abuse anyone.
