That's silly. Forcing the closure of internet chatting services because someone was stupid enough to meet some creep they met online in person, and came to a bad end? Not going to happen.

That would be like forcing every club and bar in the world to close their doors because someone was stupid enough to pick up some stranger after a few drinks and go home with them, and came to a bad end. Or forcing all shopping malls to close their doors because a child disappeared from one of them once. Or forcing all libraries to close, or restarants, etc. because something bad happened there once. Never going to happen.
