Yes. Facebook is especially bad about letting outright scammers buy ad slots.

Meanwhile in real life IG and TikTok ads are the only ones normal people seem to generally trust. I've only ever heard people talking about getting Instagram or TikTok ads for things and actually buying them in a way that would sound genuinely jarring if they said "an ad on Google."

I think there's something to be said for how IG and TikTok ads are actually made that makes them more appealing which is that they actually try to be worthwhile content to watch in a way banner ads and TV commercials just aren't.
