The ads are a window into a blatantly illegal underground economy that Meta is not only failing to moderate, but is actively profiting from and injecting into users’ feeds.
That's exactly why I've never actually tried one of these things. I had someone on Reddit message me once and give me a dude's telegraph info and it was so obviously a scam.
The dude asked what I wanted and I said something really vague and he immediately said "okay how many" without clarifying. Then when I didn't respond, he sent a screenshot of allll his notifications from messages he was getting from "happy customers"
