My facebook profile is our deceased english bull dog, I do occasionally get other bull dog owners that want to befriend me, I just ignore or delete them.....
When he ( Charlie, the bull dog ) was still alive, my wife used my E mail address so she could have access to other bull dog groups etc. I kept it in his name so no one bothers me for the most part.....
I don't use the social media at all, I just mostly have it for marketplace.
My mother in law uses her dogs profile too, seems to work pretty well.
