Not at all.

Moderation is keeping people on topic of the forum, killing spam, trolls and sockpuppets, removing abuse and so forth, and trying to keep things on the rails and civil. Including banning trouble makers. Rather like dang does around here. That's not censorship, it's attempting to avoid anarchy. Neither is limiting the range of topics the forum or platform wants. Standards and extent will vary depending on the aims of the site.

Censorship is suppressing a view, even if it follows the standards and allowed topics of the forum. Legal censorship is a little more complex as standards vary between countries.

Having a post removed because it's spam, abusive or is off-topic is not censorship, which was the point the GP was erroneously trying to make.
