Guests? I see no problem with them at all, provided they are contributing to Mudcat in a positive way, be it music or just fun sillyness...

Otherwise they are just another spammer...

Personal? Well nothing is more annony-mouse than the internet, and thats one of the up sides... You are offerd the chance to re-invent yourself everytime you connect to the net... Myself, my first instinct is to dissbelieve EVERYTHING I read in cyberspace... For that exact reason... it takes a lot of time to get to know a REAL person... to get to know someone through what their avatar presents takes much longer... And some would argue that because of the volitile nature of avatars, there is not point in trying to see past them...
