Just had a 15 year account get permabanned for repeated auto-moderator false positives. For example, quoting an Arnold Schwarzenegger movie being interpreted as a "call to violence". Most appeals get ignored. The permaban appeal was approved, but the ban remains in place and I can't seem to reach anyone there to look into it.
I was pretty upset at first, but I'm starting to see the positives of no longer being able to comment. I spent way too much time getting worked up over pointless arguments. For whatever reason, Hacker News doesn't seem to produce the same impulse.
