+Censorship is so frequent that it's hard to give just a short list of examples, especially [nowadays](21st_century.md), but here are a few:
+
+- [Encryption](encryption.md) provides mathematical ways of implementing censorship in communication.
+- [Copyright](copyright.md) enables authors to censor their works at will and enforce this censorship legally, for any reason whatsoever -- this also subsequently leads to further censorship by media hosting websites such as [YouTube](youtube.md), to mass deletions of valuable works from public archives and so on.
+- [Wikipedia](wikipedia.md) practices very strong censorship, it has a list of banned sources (calling it by an euphemism of "deprecated" sources) which include even such big media as Daily Mail, furthermore a lot of things which average Wikipedia editor dislikes are censored, e.g. the url to the controversial site 8kun (https://8kun.top) must not be mentioned in its article (take a look at page source comment, March 2024). Content Wikipedia deems harmful to someone will also be censored, resulting in removal of many valuable information you would want to find in an encyclopedia.
+- [Political correctness](political_correctness.md) is based on censorship, a great part of it is retroactive censorship and rewriting of old works, for example some populist German book publisher refused to publish the Winnetou books, a classic and important work of art, under claim of "racism"; similarly iconic books like *Ten Little Niggers* by Agatha Christie had to be crippled and renamed; the famous series Futurama is commonly censored by broadcasters (deleting words like *Jesus*, *bastard*, ...). The examples here are countless. This is used for political censorship, for example on the Internet it's extremely hard to publish any opinions not aligned with the currently ruling [pseudoleftist](pseudoleft.md) ideology because terms of service of any social media platform or even website hosting company have to forbid so called "[hate speech](hate_speech.md)" which just means anything not aligned with the ideology.
+- Pseudocommunist regimes of the 20th century practiced very strong censorship, e.g. in Czechoslovakia all public [art](art.md) such as music and plays had to pass an ideological review before being approved for performance.
+- Child pornography is nowadays unfortunately completely censored, it is mandatory to be censored in most first world countries
+- Mass shootings come with attempts by governments at censoring the messages sent by the attacker, sometimes even their names; one example for all can be the 2019 Christchurch shooting by Brenton Tarrant whose manifesto, called *The Great Replacement* (downloadable e.g. at Anna's Archive), was being forced down off of the Internet following the attack.
+- In mainstream "[science](soyence.md)" censorship is nowadays part of standard publishing process, known under the euphemism of *[peer review](peer_censorship.md)*.
+- [Google](google.md)'s search engine has very strong censorship and political bias built-in, it's done mostly by downranking targeted sites to make them practically unfindable, in some cases downright blocking sites altogether. Some of the affected sites include [Encyclopedia Dramatica](dramatica.md), Metapedia, Infogalactic, 8kun, Sanctioned Suicide and many others.
+- Censorship enjoys big popularity on the [soynet](soynet.md), e.g. there is the infamous fediblock list of blocked [fediverse](fediverse.md) instances.
+- China very intensively applies censorship to the Internet, especially in regards to the country's official ideology and [history](history.md), using the so called [great firewall](great_firewall.md). China also does weird funny kinds of censorship like removing bones from video games. Why do they do it? No one knows. Germany similarly for some stupid reasons replaces blood in video games with green liquid, ruining the games.
+- North Korea is probably the most isolated country in the world, it prevents essentially any information from behind its borders from reaching its citizens, it even completely blocks the [Internet](internet.md) and rather established its own intranet ([Kwangmyong](kwangmyong.md)).
+- Japanese hilariously blur genitalia in porn.
+- Any so called "[private](privacy.md) information" of individuals is nowadays in many countries required to be censored from the public.
+- In 2007 there was an infamous attempt at censoring the AACS DVD encryption keys (09F911029D74E35BD84156C5635688C0) which allowed to circumvent [DRM](drm.md).
+- [Nazis](nazi.md) publicly burned [books](book.md) they deemed harmful (e.g. for having been written by [Jews](jew.md)) -- though this was more of a public theatre, it was also indeed partially an act of censorship.
+- Circa 2019 [reddit](reddit.md), until then quite highly [free speech](free_speech.md) website, completely turned around and launched a censorship tsunami that destroyed thousands of communities, all just to make the site more advertiser friendly.
