Square Enix is really good at punishing people for spamming. I have never heard of a legitimate case of spam that didn't result in at least a warning. Also, if you are being a troll in a dungeon by impeding progress, Square Enix is very good at punishing you for that as well. What you are referencing are legitimate punishable offenses. Report them and you will find that the person doing them will be dealt with. What OP is talking about is someone's avatar simply standing around. Not saying anything (because they are blacklisted), not emoting in chat. Not doing anything but following OP around. That is not a punishable offense and my mother's advice holds. Ignore that behavior because it is of no consequence. Report behavior such as spamming and dungeon trolling because that actually negatively impacts gameplay.
