> Articles such as the “COVID-19 pandemic” are subject to [semi-protection](https://en.wikipedia.org/wiki/Wikipedia:Protection_policy#semi), meaning that anonymous IP editing is not allowed and that any contributors must register an account. Other articles have more extensive protections, such as the article on Donald Trump, which has long been subject to [extended-confirmed protection](https://en.wikipedia.org/wiki/Wikipedia:Protection_policy#extended), meaning that only Wikipedia editors who have been active for 30 days and who have performed at least 500 edits can directly edit Trump’s page.

If this design reminds you of the built in Discourse trust system, there is good reason for that… 😉
