why do i see so many 4chan ads on all the hard porn sites??

i know that porn users are rendered mentally insane after extended sessions, and are less discerning about what they’re using their credit cards for, but surely there’s a cap? so is it just autists and thirsty dads who browse porn and happen to be 4chan users? is it a clever ploy to get potential people on the site? are 4chan users more into amateur jerkin’?<br><br>so many questions
