How does the current blacklist/block/anti-harassment measures work?

[Alicie]

Blocking, especially anything more than the traditional old school client side ignore, is hard.

Do it wrong and it can even cause worse problems than it was intended to solve, such as the stalker issues in FFXIV or the material influence on discussion (sometimes to the point of even actively aiding in the promotion of misinformation) that Reddit's most recent iteration of the block feature has caused.

Harassment sucks, but it's important to ensure the solution isn't worse than the problem.

Currently, solution is worse than the problem

Currently, solution is worse than the problem

I would have been extremely grateful for a FFXIV-style blacklist in another game I played where I had an issue with another player who not only did not respect boundaries, but intentionally pushed against them, leaping past them in ways no one should ever have to put up with. Wouldn't call her a stalker, but I would have been very relieved to delete all that person's characters and any future characters from my digital existence, as well as prevent any other kind of contact.
