Making a playable demo is annoying too. Just deal with it, it doesnt take much trouble to tell a newbie no. Or if you can be bothered to, you could even explain to them that it doesnt work that way in a few sentences.
Even more incredibly, you could consider actually helping a newbie and showing one around... It might sound like an absurd and unheard of thing, but there are wild rumours concerning such occurences. I myself usually find that newbies are quite happy/grateful if you take the trouble to show them a few spawns, or explain a couple of things.to them. It's nice to get a little attention/help from a player, community and stuff. The kind of 'a stranger on the street saved my life' stories which move everyone.
But then again, this is Faldon, dunno what I am thinking speaking of such flowery dreams.
