These are important questions. BPD doesn't spring up out of nowhere and while there's no consensus about the cause (and frankly all the categories of fucked up people are pretty amorphous pseudoscience to begin with), it's safe to say Vickers has a flavor of personality disorder all his own.
Ralph's online antics should have botched all possibility of him getting visitation rights. All Vickers had to do was not be a complete obsessive moron in public. But Vickers has aylogged Ralph so hard that Ralph could convincingly argue to a judge it was mutual combat online between he and Vickers, and poor Ralph was just defending himself. Vickers' story of 4D chess is bullshit. Ralph handed him a victory and Vickers flushed it down the toilet and continues to flush, because like an OCD'er checking 100 times to make sure the doorknob is locked, he is compelled by mental illness.
Nice job Vickers, hope the pathetic slivers of online attention were worth it.
