You're probably right. I think it matters more to content creators than consumers? Like, posting porn to Reddit is often advertising? And like anything, people must get some form if satisfaction interactions on specialty subs. You can't just go to Pornhub and upload your favorite foot porn, right? Get upvotes, get that tiny dose of dopamine. Get to comment about how beautiful the girl is, hoping maybe she'll like your complement more than the other thirsty guys'.

Social media, man. Interaction, even meaningless... it's its own drug.
