I have nothing against rolling mauls, but adjuducate them correctly. once they start, they can't splinter and then have three forwards with no defender. That's offside.
That is incorrect. The law is as follows:
17.4 OFFSIDE AT THE MAUL
(f) When players of the team who are not in possession of the ball in the maul voluntarily leave
the maul such that there are no players of that team left in the maul, the maul may continue
and there are two offside lines. The offside line for the team in possession runs through the
hindmost foot of the hindmost player in the maul and for the team not in possession it is a
line that runs through the foremost foot of the foremost player of the team in possession at
the maul.
Sanction: Penalty kick
(g) When players of the team who are not in possession of the ball in the maul voluntarily leave
the maul such that there are no players of that team left in the maul, players of that team
may rejoin the maul providing that the first player binds on the foremost player of the team
in possession of the ball.
Sanction: Penalty kick
They are playing within the laws of the game. It is up to the defending team to maintain contact with the maul, not for the attacking team to find defenders to attach to.
