Yep, I think you might have highlighted a bug, Certain it is happening in firefox , and is not present on the android app.Have learnt to ignore it , almost always my comment has been added.
Edit yep immediately clicked on comments open new tab and my comment is here where as it is still spinning in the other tab. So probably a bug rather than overload.
This is so Elon playbook , send in the lawyers and see what happens. TBH these games are irreverent to normal people, lets de-fed from any corporate instance and just build a better community
