I must confess, I do it so often it's become the norm. When I check out someone's profile I tend to partake of the interesting experiences I find there. There I've said it, I own it and now I can live with it.
When persona non grata fan me, i often find some of my best and favorite groups on their profiles--then i block them. Shhh! Don't say anything to anybody about what i just told you or else the persona non grata won't fan me anymore :(
I'm not really a thief - I just like sharing and comparing experiences. It's fun to see or view other people's stories and how their lives are different from my own. My husband always told me, "You never know how bad you have it until you hear someone else's story," and...
I sneak around in my circles experiences and take theirs for my own and then write my own stories into the pages.
I also look for ones that don't have any avatars for the group and if I join it I try to think what would be a good one for that group.
