I too have noticed it as a PR campaign of sorts. Some have items in it that are really pushing the limits in terms of truthfulness. And due my interest in psychology, I wonder why someone would almost "gather" friends like they are collecting stamps.

In terms of tracking my email...

Just looked all around. I/"It" had my email typed in a section that allowed them to search my email account! I don't recall typing it in there! Anyway, I deleted it! Perhaps the problem is solved. It seems way too invasive to me. This software that might "compare" people...also very concerning.

Thank you Mrs. D.
