Push notifications have been instant indicators of incoming waves of abuse which both myself, and others I know, have been able to use to lock down and avoid most of it. Now that’s just gone unless you use Twitter’s own apps, which are, frankly, awful, exclusively.
There’s a reason I have something like thirty thousand people blocked on here.
And now I guess the solution is just going to be “go private permanently,” which means the social aspect of Twitter is almost entirely moot.
