I consider my recent critical post to be a deep criticism (it criticises an aspect of EA culture that is emotional/intimate and it could impact the relative statuses of people within EA including prominent figures) and I wrote it under pseudonym, so I’ll add my personal perspective. I don’t think this post captures why I wrote my post under pseudonym and I don’t think decentralising EA would have caused me to post it under my real name.
I’m also not sure exactly what message we should take from many people using pseudonyms. Here are some possibilities:
People are rightly worried about retaliation
People are wrongly worried about retaliation
The community is unusually open to criticism and will seriously consider criticisms made even under pseudonym, so people feel more comfortable using pseudonyms for various other reasons including personal ones
Other possibilities I haven’t thought of
There’s probably a combination but I don’t know how we could determine how much is of each. On a positive note I think most other communities would simply disregard deep criticisms made under pseudonym or would try to dox the authors of such pieces, which is not something I worry about here.
I think if you’re focused only on reducing sexual assault then your point makes sense (I don’t think an abuser will read my post and think “oh okay I won’t assault people then”), but I think if you’re focused on things like reducing the extent to which EAs feel pressured or creeped out by being subjected to certain behaviours then it’s still helpful for people who are not the “worst offenders” to avoid these behaviours. I think both are problem worth addressing and other mechanisms are needed to address sexual assault.
