Cryptocurrency and blockchain related posts get flagged quickly because the signal-to-noise ratio is low (some would argue it's zero). There uses to be lots of posts with interesting-sounding claims that didn't hold up under scrutiny from actual CS experts, and I think HN got sick of that. Then you have the pump-and-dump astroturfers that try to hype up certain coins, and those were always flagged immediately. So long story short: any good actors in that space have been drowned out by the bad actors and idiots.
