@strawberryfieldsforever @blueberry it’s a “administrator/owner” who has the ability to make the rules of each individual instance. Some have more loose rules while others are far more restrictive. There is no common set of rules amongst the fediverse. Etiquette, yes. Rules, no. The rule you mentioned AFAIK, is aimed at helping people who have anxiety issues. How effective it is, is not for me to say. But it is a popular rule none the less.
