in this case he pretends he's been a victim of foul play, when no such foul play happened
I disagree totally. McGahan was definitely a victim of foul play..Samu Kerevi pulled McGahan's jersey, and when that didn't slow him down, Kerevi pulled his arm & shoulder back
[LAWS]Law 10.4 (e) Playing a player without the ball is dangerous play.

[LAWS]10.4 (f)
Playing an opponent without the ball. Except in a scrum, ruck or maul, a player who is
not in possession of the ball must not hold, push or obstruct an opponent not carrying the
ball.

The issue for me was that McGahan made it out to be a lot worse than it was. His antics were to draw attention to the foul play; he certainly did not make it up out of whole cloth, but it is still completely unacceptable behaviour in my book.
