I used to work with a friend of mine from school in a business park that had dozens of tech firms - on the smaller side. The biggest had 100 employees but most had a dozen, maybe 30. We would see them start new guys and probably once a month my friend would see one of these guys and say "he's a pedo" and it was creepy because the police turned up and arrested an awful lot of the guys my friend said that about... There are A LOT of them in tech.
