"Wrong" can mean so many things.

Removing misinformation isn't censorship, for example. Similar with removing off-topic threads or comments.

Removing illegal content is censorship if the law is unjust (eg. political dissent restrictions) but not if the law is just (eg. CSAM removal).

Removing immoral content is way dicier, because morality is not fully mapped, and what one person thinks is immoral might seem perfectly moral to another (eg. blasphemy or profane language). I personally would not removed content I found immoral unless it violated community standards, and would consider such removals an overreach but not censorship unless it was selectively targeted at an individual or group.

I guess by my lights to be censorship it has to be:

• subjective

• unjust

• systematic

Removing something objectively incorrect or in the wrong place is not censorship. Removing something justly proscribed is not censorship.

Removing a thread when one viewpoint or group posts about it but not when another posts about it IS censorship.
