How would I do sanity checks with a placement system that uses models?

So I have a system which allows players to resize the models

Now the Problem

HOW WOULD I DO SANITY CHECKS ONTO THE MODEL

Do I trust the players model from the client that they resized ENTIRELY?

I was thinking of something like

Player sends a model to the server ---->>>> Server checks if that model from the client is under a folder

so like

Client Side

RemoteEvent:FireServer(ModelToResize)

RemoteEvent.OnServerEvent:Connect(function(Player, ModelBeingResized)

	if ModelBeingResized.Parent == PlayerFolder then
		--Resize it
	end


end)

I would suggest that you add a check that checks if the model is sized larger than its largest allowed size. Also, I would suggest that the models exist in Replicated Storage, and both the client and server just pull from there, so that the client doesn't end up sending a model that shouldn't be there. You could implement this by sending the name of the model, and the size it should be resized to, instead of the entire model.
