Tbh based on his track record I would bet that Suarez probably did say something and that there probably will be a punishment coming up.
The person that has made the accusation isn't relevant. It'd be like saying that a player who gets taken out intentionally and has his leg broken shouldn't receive treatment, and the player committing the foul should get away with it, just because the guy who got his leg broken did a lot of diving or play acting in the past.
