I understand the add-on itself isn't using eval to do bad things or anything, it just looks like you're using eval to mess with clients on your server via this add-on. I retract my earlier statement about being on the fence about failing it - I can't see any reason to. That said if this does start adding GUI downloading then that's another kettle of fish.
The problem here just seems to be DrenDran not being responsible with the power this add-on gives the server over the client in this case, but I don't care too much about that personally.
