All the posts that got my accounts killed had one thing in common, I posted something against HN. Cant it even take criticism anymore?
The point I want to make is that when participating in a community, there is usually a natural feedback process that allows one to discover the rules and values of that community. If one does something out of line, the community will swiftly react. Multiple negative reactions are a sign that one's behavior isn't in line with the community's standards, and should be used as an input to the decision-making loop that says, "Wait, maybe they don't like it when I do X all the time." Then, you either decide to adapt to the community, or you leave.
Also, most communities will only accept a limited amount of correction from any given source, which varies by source and by community. One of the behaviors that's likely to earn repeated negative feedback is trying to change the community more than allowed by one's standing within the community.
Long live HN Skynet!
