Are self-moderated threads censorship?

[hugeblack]

Censorship is the restriction of what others say in a particular formulation and prevents any transgression of this formulation.
This forum leaves you free to express your opinion but sets conditions. As long as the replies are relevant, your post will not be deleted.
Local rules are censorship, as I prevent a particular person or idea from being within the wording. For example, it is forbidden for @XXX to reply. It is forbidden to talk about LN in a topic that talks about Bitcoin scalability problem and so on.
