Effort matters.

This won't solve a dedicated stalker, but it will discourage a troll who scrolls twitter like a normal person.

You're quite right that it's trivially easy to work-around, but if you just use a main account 99% of the time you won't even know that you have something to work around because you're not seeing the posts you want to attack and sick your followers upon.

Twitter is mostly entertainment, so most people will use it in the way that's the most convenient. That means "hide posts from people who blocked me" should make a decent dent in that kind of negative harassment.

Yes it won't stop somebody who treats hating people on Twitter as their job but how many of those are there?

So we're supposed to thank him for selecting the ugliest brute-force solution?

It's not security theater to offer a user settings that help them tailor their experience. People aren't mad about stalkers being clever, they're angry at X for not giving them better options. If your social media doesn't let users voluntarily segregate themselves from antisocial behavior, it shouldn't surprise you when they want to leave your website altogether.

It's hard to take this seriously when it is so laden with name-calling and bitter sarcasm. There is nothing ambiguous or complex about either side of the argument. If you can't defend your side of the argument without falsely accusing the opposing argument as being non-existent or factually incorrect when it's laid out so clearly (see siblings, or any responses any time this comes up), you should stop and come at it from another angle.

And, to be clear, this is not me saying that one side of this argument is correct and the other is wrong. I just think your attitude is non-constructive.
