I see you've never accidentally really pissed someone off in a comments section about an inane topic.

I got e-mail blasted on my linked e-mail here for a user called u/Loughla on reddit (who has deleted their account now). It's not me. It was never me. But oooohhhh boy did they upset somebody in an anime subreddit.

In other words, angry people absolutely will go the extra mile just for some feeling of vindication or other nonsense.
