Is it wrong for birth parents to track down kids they gave off for adoption on Facebook?

[Allie]

I'm adopted and i know whats it's like to be on the child end of it. Growing up i always wanted to know who my birth mother is and, where i got my hair and my eyes everything. The main question i wanted to know was why i was given up. if i was in that situation where my birth mom contacted me i would have so much emotions going on and, unless your adopted you wouldn't know what it would feel like. I would rather see her in person for the first time than on the internet. when your in person its real and, seeing her would help me to understand better and maybe feel national connection with her. Plus that might not be her you never know who's on the other side
