High Noon: OK To Spy Via Facebook?

On Facebook, Sidekick Cindy confesses to checking out her son Alex’s date’s Facebook profile page to get some idea re: the girl his boy was going to date. And she admitted feeling a little guilty that she had. But other moms responded she had done no wrong. Said one: “Oh, I am definitely going to cyberstalk all of my kids’ dates. That’s just good parenting!” And another: “You only have to feel guilty if you post her name and get everyone to also go check her out… And then allow everyone to discuss her flaws…” And still another: “No, I have three girls and it does not seem unreasonable to me.” I noticed that no men responded to the inquiry.

Question: Is it OK to check out the Facebook pages belonging to someone who is going to date a child of yours?
