@AnarchoNinaWrites Almost everyone I know who joined fedi and left, left because they were welcomed with a bunch of messages telling them social norms they had to adopt out of nowhere.
Even though it is sometimes well intentioned, my friends got messages telling them about alt-text, CWs, chatting with the "wrong people", how they shouldn't ever post anything with irony, etc. So, they left.
When I first joined in 2016 we just encouraged people to send new folks a " 🍍 ". So, you would suddenly get tons of messages like "welcome, have a 🍍 ". It was way more fun, still built a distinct culture, and made it more inclusive.
