From my skimming of the Twitter account linked, it’s something related to hydrochloroquine. I can’t speak to the effectiveness or lack thereof of this compound for treatment of anything, but I have seen a lot of sites crack down on anything pro-HCQ, which may be justified if it is a vector for coordinated behavior otherwise forbidden by TOS.
