Manual vs automatic is irrelevant here. There was much less content to moderate if we talk about media. They could censor every single publication, movie or song manually. In oppressive regimes like USSR the censorship is total - the only escape is your kitchen (if you can really trust the people you talk to), in the West you are free to choose the platform and live peacefully in your bubble if you want.

In oppressive regimes like USSR (as if there are or were any regimes "like USSR") (where censorship was manual) there always were loopholes to avoid censorship and convey messages you wanted to. In the West (as well as in the East) today the platforms don't allow for any loopholes, or even when such loopholes are found, they're being censored out very quickly.
