The major troll gang of 2016 is gone. The only one left doesn't post here hardly anymore and stopped making alts a while back. She also likes the latter day trolling by the real MV, so no animosity there anymore
Another of that group got on the bad side of the rest and was downvoted to oblivion by them. The other 2 left for other reasons beyond their control.
So pretty sure PB is none of them, different style also.
