PubPeer is a central place to anonymously comment on any academic paper. It has what feels like an archaic UI, hasn't improved very much since it was first created but has led to numerous high profile retractions and fraud findings in science. Anonymous comments have been a very important capability to call out problems in papers from high profile scientists.
There have, in previous years, been comments on a number of "transgender" pieces that make unscientific claims in high profile journals, e.g.:

I can confirm that new comments on similar sorts of papers are not being published on PubPeer. The moderation process is entirely opaque. A great shame given how important PubPeer has been in raising flags about terrible science.
It's really a shame the whole scientific community has been indoctrinated by transgender ideology, so much to the point that some organizations are saying it isn't even a mental illness. Body dysmorphia and gender dysphoria share many common symptoms, so why does one group get their feelings/delusions affirmed and the other doesn't?
