Well in my book, any tactic that make a non consensual PVPers (i am being diplomat here) cry and/or shout angrily at you is a good tactic whatever the devs may think.
In this game i avoid being seen so i am not in trouble at all but should it not be the case i'd use it without remorse .. worse, to make my day i'd try to make you agro NPCs before cutting the line so you would be screwed twice.
