I think I saw that loser shouting a few times near Gridania's aetheryte. Don't worry, most people know that someone spreading a hateful message about someone day after day is usually the unhinged person. No one normal does that.

You are right in saying that square needs to do more to stop harassment, but I'm glad you have found support from players and I hope you are able to enjoy the game despite these incidents. Gz on the house!
