They intentionally created a system which resulted in a user being unintentionally shadow-banned. Creating a shadow-banning system isn't malicious. Creating a shadow-banning system that accidentally shadow-bans legitimate users is pretty obviously more a case of stupidity than malice. Just because they created the system intentionally, doesn't mean unintended behaviours in the system are intentional malice

The maliciousness comes in with the self-interest. They're lying to you because they make more money when you don't know to complain.

They aren't like baby killers or anything, but they are certainly prioritizing their wallet over your consumer good and even safety.

Imagine if HN charged to post and shadow-banned users.
