I accidentally bypassed the filter in my game! How do I fix this?

Basically, I'm connecting a chosen player's chat message to a RemoteEvent that displays whatever they say on everyone's screen.

--Script

game.Players[rapper.Name].Chatted:Connect(function(m)
	if workspace[rapper.Name].RapCheck and workspace[rapper.Name].RapCheck.Value == true then
		lyric = m
		cd:FireAllClients(lyric)
		else return end
end)

There's a whole framework surrounding this, but I'm sure the fix here is simple. Thanks in advance for your guys' help!
