Square Enix Does not care about Stalking/Harassment In Game

[SamSmoot]

One solution: An ignore player option that makes the ignored player disappear completely from the game in your view, You don't see any evidence of their existence at all. I suppose it could also work in reverse, so the ignored player wouldn't see anyone who ignored them.
This would have to apply to ignored player's entire account though, to stop them from creating alts to continue the harassment.
