I couldn't agree more.
Pre meditated and planned deception with the intention to cause distress is W R O N G. In this case, a minor and a vunerable minor it is heinous

How would you like it if you joined a dating website after a bad break up and someone started pretending to court you? Then used the private info and the situation to cause you public and personal distress?

It would be enough to get to anyone but never mind someone so vunerable.
