>>14146803tl;dr version - a few years ago 8ch got nuked and all their schizos (actual fucking nutjobs, not the harmless larpers we used to deal with) migrated to 4chan. Since then there's been a measurable increase in the number of fake space, flat earth, free energy, inside job, electric universe, relativity fraud, time cube, psychic alien ghost bullshit on /pol/, on /sci/, and on virtually every other board.
