I am not, but I can downvote things that I think degrade the quality of discussion, which in my personal opinion includes a great many Covid threads. Others of course can submit and upvote stuff they find is interesting. If you have good stuff that challenges the conventional wisdom, please post it, as I actually seek out that kind of material (for example, Alina Chan's Twitter feed, which in my opinion is the best skeptical source on the lab leak theory).
