You obviously have not read any of the threads at all. Nobody has been asking for the removal of the aethestics in regards to posting from our characters. Take my word from the original thread:
This is based on what facts? BattleTags actually reduce the harassment, as it is far more secure than the character-server. I mean, for all you know, I could add you’re character-server to my friends list, and follow you everywhere, and you wouldn’t even know about it. BattleTags doesn’t even work like that.
You’re BattleTag is a public nickname, used to identify your BNet account. You seriously do not know what you are saying.
Go to the other Blizzard owned platforms, and point out where this is actually happening. I’ll wait.
