Facebook Manipulation: Good or Bad?

So, my wife is a proud supporter of Facebook Manipulation.  Here's the basic idea -  If a guy you're dating starts acting weird and wishy-washy and doesn't really seem to know what he wants, start posting photos of yourself being touchy-feely with other guys and have other men post flirty messages on your wall.

My wife used this tactic on me during a week we were dating where I was saying I didn't know what I wanted.  So, Monica (my wife) said "Well, until you know what you want, I don't want to see you or talk to you.  So, figure it out."

Next thing I knew, she was posting photos like this:

Within days, I knew that I wanted Monica.  Whether or not this was due to Facebook manipulation is still a topic of debate (Monica says yes, I say not really).  Since that time, I have been recruited a couple of times to help my wife's friends who get into similar situations with the men in their lives.  

This girl was dating a guy long distance that was giving her the run around.  After this photo (among others) was posted, he started to come around.

Monica also had me post a flirty message on one of her friend's walls when the guy she was dating would not call for a few days, then randomly call her to "hang out" (booty call).  Here's what Monica (we were just dating at this point) had me post:  
 

Rhett Maurice Billen KYLIE! Hey, I haven't seen you in sooo long. I hear there's a Green House Party on New Year's. I should be back in town by then. Me + You + Hot Chocolate + Green House = A Happy New Year. What do you think?

In closing, I'm interested to know how many people condemn Facebook Manipulation on the grounds that it is sneaky, deceiving, and immature, versus those who support this tactic with the attitude that it's all in good fun and no one's getting hurt and it's just something to laugh about in the end.  What do you think?
