Friend endlessly stalked and harassed by another player on many characters

[LibitIncarne]

Someone I know is being harassed often, and when they ask the harasser to stop, the person doesn't reply, disappears, deletes the character and makes a new one later with a different name to do the same thing.
So blacklisting doesn't work in this case, and they haven't been able to get screenshots effective enough for the harasser to be punished

They considered switching regions to get away from this, but transferring and name changing doesn't help as the lodestone page keeps the same URL ID, so the stalker is able to see where they go to and what their new name is.

What can they do aside from quitting the game? And why does blacklisting not hide a player's entire account?

Blacklisting DOES hide a player's entire account now. What are you talking about?

Does that only block characters that existed at the time when they get blocked or also every character that gets created in the future?

It blocks their entire account, so any alts they have or create will be blocked too.

It blocks the service account, which includes all characters created before and after the blacklist is enacted.
