There's a guy saying that it's actually possible to see if an exploit is attached to the client, provides no proof and of course seems to not know anything about RBXLua or how it works, this is most likely fake, any thoughts on this?
(Claims no script is executed using exploit, just exploit injected)

I think I remember one dev found out a way to do this (detecting injections), but I believe exploiters found out about how it worked and mostly patched it. I mean if you can prevent executions that's just as good isn't it?
Sources?
