I got ecchi dolls (China knockoff, cheaper but decent) from a site called OtakuCrate once, they've emailed me to confirm that the R18 loot is back under new US regulations, which means future orders just require your legal identification. I live in Europe, so there's no damn way I'm conforming to any privacy-invasive law, and I'm also not stupid.

It can be both. Reddit has a history of fabricating conversations. The way they sell advertising implies a certain level of engagement from their user base which can lead to bots pushing products in the form of reviews or by mention.

I think it's worth noting that Reddit, at one time, did have third party bot protection; however, it only protected their advertising. I can only imagine what the rest of their traffic looks like, but I would not be surprised if they were using bots of their own.

Like you said, they can make some money selling your information but they can also control the narrative how they choose.
