If you're going to accuse us of doing something bad, please state clearly what "it" is and give specific links so we can look into what happened.

I'm guessing here but it could simply be that any moderated forum is effectively censored, HN included.

In my experience almost all dead comments I've seen deserve to be dead.

Down votes are more hit and miss I find it depends on the crowd that are attracted to that topic. E.g. Microsoft submits seem to be biased as pro Microsoft etc. That may be where the echo chamber effect comes in.
