@holothuroid TL;DR is often accompanied by a short summary, so that those who didn’t read can get the gist of what the text says. Posting tl;dr as a way of telling off the author for writing a text too long for you to bother reading it is just rude and ignorant.

If the reason for posting pw;dr and ai;dr is to tell off the author, then one is simply showing one is a rude person more concerned with signalling virtue than engaging as an empathetic human being.

The only way to deal with posts that you can’t/won’t read for whatever reason is to move on. Quietly.
