Genuine question

How do people take so long to track down illegal sites like you can literally just go on google and search "manga free online" and there's like thousand websites NOT SAYING THEY SHOULD but that's just kinda dumb and imagine one of the investigator is an imposter and is secretly an active user on these sites gooning omg are there any police officers who secretly goon to yaoi and yuri on here so far I've seen all kinds of age groups and all kinds of people married with children so I don't think I'd be surprised if a police officer goons to yaoi and yuri smut on here as a daily routine
