I think it would have been fair to have a rule saying “no surgical modifications”… because doing things like facelift, nose-job, breast/buttox implants, cheek lifts, wrinkle removal, etc, are obviously unfair advantages (in a beauty contest) for those who have the money pay for it; and having a generic blanket rule like that would have accomplished the same thing they were trying to accomplish without being so blatantly transphobic… so a rule like what they have only proves that they are both despicable AND dumb. The entire notion of beauty pageants is outdated and stupid if you ask me.

A lot of community types just simply don’t work without a minimum critical mass of members.

Imagine asking a programming question on a software development community of just 5 people. You end up with 3 people who aren’t active enough to see the question, 1 person sees but doesn’t have an answer and doesn’t respond (classic lurker), and one person sees it and responds that they don’t know the answer. Now imagine a community of 5 thousand people…it’s suddenly much more feasible to even bother asking the question.

Sure, fediverse could exist with just 5 people, but it would be worthless and pointless.

It happens to email ALL THE TIME, we just call it something different when it happens to email. Evaluating email for SPAM potential is an every-day common place occurrence, and for at least the past 10 years, a factor called ‘domain reputation’ is part of the equation. Entire domains get spam blacklisted because they refuse to enforce rules for their users. The end result is that some domains completely refuse to accept mail from some other domains.

Blacklisting an entire domain can and does happen daily. It just doesn’t have the same triggering ring as the word “defederation” has.
