The OP would have to weigh in, @Tanako , but that doesn't feel like it was their first engagement. Just guessing based on @Tanako going for the launch codes on their first reply of that sequence.
At this demonstrated point of their interaction...sure, block and delete makes sense for this particular creator. However, one size doesn't fit all.
Like I've repeated, every situation is different.
Trolls come in all shapes and sizes... A troll could just as easily be a 13 year old girl as much as a hulking psycho killer. Everyone's tolerance for it is different, no judgments.
The intent doesn't have to be changing the trolls mind, (though that's IS possible, unlikely but possible) it can just be about defending/representing your work in the eyes of your other readers. At least, to a certain point.
