I always look up my T's. lol. It's natural to be curious.
I don't think it's considered "invading" anyone's privacy. What if your T looked
you up? You would never know!
Nothing is private on the internet anyways. I would
hope your T understands that. So, if she willingly puts stuff on the internet, she should expect that people will look her up, and that nothing she puts there is private.
