I'm fairly certain I enabled all possible privacy options when I installed telegram. I went to specific lengths to do so. I still get "xyz has joined telegram!"

I'm fairly certain I enabled all possible privacy options when I installed telegram. I went to specific lengths to do so. I still get "xyz has joined telegram!" when a new friend joins up from my contact list. Yep: just checked. Nothing more I can do to increase privacy settings. Zero confidence in it after that
