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.
For a site like reddit/lemmy, more is better. You need enough users that you can find any niche community u want.
I guess I would rather have less bots, trolls and angry assholes than have more niche communities.
