I follow a bunch of YC founders on X. Lots of behavior that could be construed as 'growth hacking - or 'deceptive' depending on your bent: promoting open source libraries that don't work, rewriting tweets from smaller accounts, coordinated replies from mutuals and so on.
I guess that's the game, but they do seem a lot more cavalier about it of late. Increasingly resembles the crypto 'community' (derogatory).
