I think social media is what makes them dangerous now. Even a harmless theory can get twisted or amplified by algorithms, reaching people who don’t have the tools to fact-check. That’s how harmless ideas become real-world problems.
Yeah, algorithms basically give everyone their own echo chamber. Even the “fun” conspiracies end up validating the “serious” ones for some people. It’s like a slippery slope, what starts as curiosity can spiral into obsession.
