Nobody wants to say it aloud because of the legal implications, but the majority of the internet is literal underage children. Like, probably over half of Discord users are actual kids who are vulnerable to being scammed when an account dupe of their favorite YouTuber friends them.
This has the effect of making the average user quite stupid, because they're too young for intelligence or wisdom - but as long as they sign up and promise they're 18 ("really!") then they can be advertised to.
