There is basically almost no precedent to todays problem of misinformation spread, so historical examples are near useless. Censorship is a trivial problem to overcome in the modern world contrary to the last century’s vision, one can’t really hide anything on the internet. The censored information itself will be available in some way. What is much more effective in preventing information flow is the other direction, obfuscation or overloading of information.

A great example of it is an older Russian voting fraud, where video footage leaked of a man repeatedly throwing in ballots. It got quickly shared over Twitter with the name of the town in hashtags — there was no chance of censoring that. The solution was to spam twitter with unrelated bullshit with #NameOfTown, effectively putting out the flame.

And unfortunately bullshit like antivaxx, anti-climatechange, and political campaigns do use this technique very effectively to counter the usually more complex scientific arguments. People prefer taking only a few logical steps instead of the whole “we create the replica of parts of the virus by injecting the …”. Unfortunately I don’t know what would be a solution to this. Perhaps better education..
