The image is a reddit post with the following text (automatically transcribed):
I remember I got into an argument on reddit awhile ago with a person over Italian food. It got to the point they were following me into other subs to harass me. I clicked on their profile to block them and their most recent post was them drinking their own piss on r/piss. At that moment I realized I had spent so much pointless time arguing about the taste of food with someone who drinks their own piss as a hobby. This site is a shit hole.
This is the issue that’s so hard to see until it is explicit like your example. The time wasted, not spent on things of value is where this type of trolling costs us the most. In world news there were well thought out answers to some asshole who was just giving low quality taunts
World News and News were the worst. There would always be one accepted reaction to every post and anyone veering from it was downvoted into the basement at best.
