Can you block the default gmod Taunts?

We have people on our server using these taunts in the middle of gun fights and it messes with the hitboxes and makes them hard to kill. Is it possible to block these taunts or overwrite whats returned when its called?

Just freeze them if they are taunting.

Directly from the base gamemode:
Name: gamemode:PlayerShouldTaunt( ply, actid )
function GM:PlayerShouldTaunt( ply, actid )

-- The default behaviour is to always let them act
-- Some gamemodes will obviously want to stop this for certain players by returning false
return true
