Real ID in game issues

My post warning folks about real id in game was deleted. I will be more civil in this post.
In case you didn't know, you can find out the RL names of your friends friends via Real ID. Another post pointed that out and I confirmed it is true. I was able to click on my RL friend and see the RL names of his friends.

Also, other posts have warned that add ons do screwy things with real id, like posting the rl names of folks, so be careful with add ons. I don't know if it is true, but in any case, Id use caution.
