Are you freaking kidding me? You want to remove such a great feature for a silly reason like this.
Why the rest of use have to suffer, because of one aspect that happen any way in less than 1% of cases.
There will always be some stupid kids that will use any mean possible to annoy you, but this is not a reason to remove such a great feature.
I am not a very social player, I do not have a clan, I mostly play solo, but when I started to play, I had to accept that this is a multiplayer game, so instead of proposing such stupid ideas, you better consider playing single player games.
