The thing is, everyone already knew that child and human trafficking is a big issue in this world. No one needed to wade through the cesspool to find that out. But 4chan doesn't actually give a damn about the kids. They got obsessed with phantom sex cults under pizzerias and decoding gematria in emails because they wanted to undermine Hillary Clinton's election and because they got completely washed by actual non-ironic nazis who believe all "leftists" in power (IE the Democratic Party) are pedophiles because they equate LGBT with pedophilia and, by extension, Democratic support for the former with a likely predilection for the other.
And then they came up with QAnon, not out of any sincere concern for "the children," but just as a shitpost that took off because it was too on the nose, and now legitimate efforts to curb child abuse are being hamstrung by this insane obsession they've bred into the zeitgeist to see trans people as "groomers" and secret pedo conspiracies everywhere.
And yet, even though they'll gladly take credit for it, none of them saw Epstein coming. Sure, one anon posted about Epstein's death before it hit the news. That's about all they can legitimately take credit for, but overall they've done more harm than good.
