To give you just one of many examples, there were many many negative comments in the Core 30 announcement thread pinned on this section. They all got deleted and only the two posts positive towards core remained. Now some negative comments were posted again. Let's see how long before those get deleted too.
Just checked out the thread and I saw it's self moderated.
And if you read the top you would see this.
This is a self-moderated topic. If you do not want to be moderated by the person who started this topic, create a new topic
It's quite a normal situation
Once you post in such thread, you already agreed that the creator can moderate your post
And the thread moderators actions doesn't represent Bitcointalk.
I can create a self moderated post and when I feel someone is going off Imo or something I can choose to delete.
So Bitcointalk doesn't censor posts.
Who's acknowledging censorship?
How you feeling is how some feel about the strict filter of knot and definition of spam.
There's a likelihood this thread would be moved because it has nothing to do with Bitcoin.
