This isn't censorship, this is HN readers saying they're not so interested in the memo that they need to have another post about it every hour.
If it is upvoted enough to reach first page then it means there are HN readers who are interested.
We've turned the flags off on this one and ask that users please take care to post civilly and substantively.
I've learned a lot from HN, even changed my views on at least one big issues (legalizatiin of certain drugs) thanks to what I read here.
That happened because 1. reasonable discussion where allowed and 2. I read both sides and decided the other side where right.
It wouldn't have happened if every discussion about it had been flagged off the site.
