I ain’t saying you’re wrong or your points are invalid, but bear in mind that Lemmy is a very young piece of software. It will evolve to cope with these kind of issues and if the lead devs don’t step up, then - as was seen in the near-recent CSAM attacks - the community will and develop it’s own set of tools/plug-ins.
All social media type software goes through a kind of perpetual arms-race with bad actors and whilst it’s not impossible, it’s often very difficult to anticipate what method the next lot of bad actors will chose to attack the lemmyverse with.
Free speech is a good thing. Absolute free speech is the excuse shit people use to air their shitty opinions.
