Here's the thread where I discovered this: https://www.reddit.com/r/C_S_T/comments/feql8u/is_the_coronavirus_being_found_in_peoples/fjpyrbv/

This was the original paper, showing HIV insertions to the Covid-19 virus: https://www.biorxiv.org/content/10.1101/2020.01.30.927871v1.full.pdf

If you post this shortened link to it anywhere on reddit, it instantly will delete your comment: https://t.co/h6xPX1gYvj

It will show your comment to yourself if you're logged in, but if you log out you can see it's deleted and no one else can see it. Normally that's behavior that I see when an entire account is shadowbanned, but now they're apparently doing it on a comment-by-comment basis. To silence scientific papers.

It looks like that journal also forced them to withdraw the paper.

If it was a bio-weapon and they wanted to cover that fact up, that's exactly what this would look like! Anyone else find this extremely concerning? Try posting the shortened link on reddit yourself and see your comment magically get shadow-removed within 2 minutes.
