We've banned this account for repeatedly breaking the site guidelines and ignoring our many requests to stop.
If we allow users to harass and attack people who have genuine expertise for posting here, does that make HN better or worse? Obviously worse. Mob behaviors like this are incompatible with curiosity.
Why would anyone ever trust a goddamn thing you have to say about their data?
Unless they pay your salary and are asking you to give your expertise on hoarding and abusing user data, obviously.
