Getting rid of the block function is like trying to run email without a spam filter. Elon musk/ Twitter was already out of control. Now they’ve completely lost their minds, even more than they already had.
There’s still mute but that weirdly makes things worse - now you mute someone but they can still reply and interact with your tweets except you can’t see it. So the abusers can just spam the shit out of you, doxing and w/e and you’ll never know.
