Gacha games are famously deceptive and exploitative.
Airbnb has a good justification for keeping the location private, but it's typically pretty hard to get an idea of the value you're getting for your dollar until you actually arrive on site and discover just how functional the HVAC/kitchen actually are and how good the location actually is.
While you might not classify any of the three as "scams", they're certainly classic 'low-rent' advertisements for things that take advantage of information asymmetry to convince customers to pay more than they would be necessarily willing to if what their money got them was actually clear.
Micro-Targeting is one of the worst mistakes of the entire advertising industry and we'll be probably dealing with its consequences for a while to come.

How are these not scams?
I don't relate with this at all. I get ads for normal insurance companies, uber eats, air bnb, and gacha games to name a few. None of them are scams, so I can't understand understand why so many people on hacker news complain about scams.
Do you live in a region with barely any ad inventory?
