I'm not following how blocking this handful of users involves "getting really good with personal filters". In jerboa it's like three taps to block someone, and the last time I used voyager or lemmy through a desktop browser it was similarly easy. And how does blocking people uncritically posting that content risk blocking people bashing AI?
This just seems like a repeat of the witch hunt post about the db0 instance a few days ago. I can only speak for myself, but the last thing I want is for this to become some sort of community where we organize against specific users or communities. Fighting amongst ourselves in this little slice of internet social media will have no effect on the actual companies and market forces pushing this slop.
A big part of what makes lemmy what it is is that people aren't doing that sort of witch hunt shit here. If you want to curate other communities, then make your own copy and enforce your rules on it, or work your way into their mod team.
Most of all, you can lead a horse to water, but you can't make them drink. And holding their head under just gets you a drowned horse. Speak out as you can and curate your own experience.
