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

[AnonymousGuy]

This happened with my brother, adopted as a baby, as the birthfather found him via Facebook. The birthfather is a good man and he had the best of intentions but my brother was 16 and it would have been handled much better had he gone to the agency and my brother's (mine also) parents (the adopted parents who raised him) and work out the best way it can be done. In the end they are close but the birthfather should have done it through the agency or a counselor as my brother and parents didn't even know who he was since the birthmother never described him during the adoption for privacy reasons so all that was known was that a birthfather existed. Five years later they are close though and the reunion was good, but contacting through facebook was a mistake.
