there's a bug that causes some requests to just get stuck processing on the server side. The comment/etc. will go through, but it will never reply to the client indicating success. The client side eventually times out and you get the toastify message after a long while, but by that point people have often re-submitted multiple times attempting to make it actually visibly go through on their browser.

Where it gets extra spicy is it seems to happen on posts made by certain user accounts more than others (or possibly exclusively, but idk). You are one of those accounts, so on your posts specifically it happens way more. Idk what could possibly be so special about your account but something is fucked
