There's nothing wrong with forum users criticizing the way we post. It's part of the give and take that helps set the informal rules that make this forum work. Thanks to the self-policing, the mods only rarely get involved.
I also think that some people are too thin-skinned. There's a difference between criticism and censorship. If you think a critique of you is unfair or too harsh, why should you care what some anonymous idiot on the internet thinks about you? Defend yourself if you want, but don't take it personally.
