Yeah, I don't consider moderation censorship. There are plenty of places to go for unmoderated conversations, but they are rarely civil. On Metafilter, abuse and insults aren't tolerated.
Not anymore, unfortunately. Metafilter used to be a great community 10-15 years ago, but these days it is a heavily censored echo chamber.
Have an upvote. The "Note: It is allowed to cost money." reminds me that the $5 charge on MeFi filters out alot of noise. However, this doesn't necessarily promote an increase in quality. Much of the discussion can be, like Reddit, cute or snarky one-liner comments.
