Sounds exactly like my experience going through the shadowbanned comments. I understood a few of them (like my recent comments suggesting Lemmy). But others were exactly like what you described. They were comments I spent an hour mulling over at times to get them just right with the right nuance and resources. So sorry that this was happening to you too.

Btw, for anyone mistrusting this tool, logging out and viewing things as public or from an incognito browser window should show the shadow banned comments as “removed”. Obviously difficult to do for large scales, but that’s why there’s a tool I guess.
