Remove a specific face from a roblox player?

I am making a game and theres this face which i dislike and is it possible to remove for example

a person with ninja face joins and their face turns into the default smile face when they join

the scripts parent is workspace

local p = game.Players

p.PlayerAdded:Connect(function()
	local char = p.LocalPlayer.Character
	local wa = char.Head:FindFirstChild("face")
	if wa.Texture == 11453609 then
		wa.Texture = nil
	end
end)

if theres something wrong with the code please tell me

i dont own the ninja face so i cant test it and i dont know if any of the answers will be correct

Check new Decals that may contain the faces you want to blacklist. I would personally use table.find to check a list out of convenience.

workspace.DescendantAdded:Connect(function(FaceInstance: Decal)
	if FaceInstance:IsA("FaceInstance") and table.find({
		[1] = 1234567890,
		[2] = 1234567890,
		[3] = 1234567890, -- List your face blacklist here.
	}, string.match(FaceInstance.Texture, "%d+")) then
		FaceInstance.Texture = "rbxasset://textures\face.png"
	end
end)
