Ben Pluimer one of the co-executive producers and director of WWE Swerved which airs on the WWE Network recently took part in an "Ask me anything" on Reddit. He confirmed that there was intial backlash from WWE Superstars to the show when it first launched and there was a "DO NOT SWERVE" list.
"The backlash was real. When superstars heard about the prank show, we would have to sneak into venues through back doors so they didn't see us. They got to know some familiar faces and if they saw any of us, they would spread the word. Sometimes they would walk through a prank set and see our camera hides and give them a little bump.
It was pretty nerve wracking at times. There were several superstars we were not allowed to prank no matter what. If one of them wandered into our "set", we had to freeze and wait for them to leave.
Apparently there was an actual "DO NOT SWERVE" list."
Pluimer added that WWE talent relations were in charge of allowing who got pranked:
