Voluntary tackles have gone the same way as raking from marker, hooking in the scrum and use of the sin bin.
How about defenders just stand there and point at him, forcing the ref to penalise it.
That would look pretty funny actually.
First of all.. High five for having the same name as me.. and a double high five for rocking the He man figurine as your pic. "by the power of grey skull He-Man!!" haha awesome.. good times..
As for the tackle.. well.. I dunno.
I think it can only be penalised as a voluntary tackle if the player actually plays the ball without a tackle having been made.
