I've noticed that whenever guest posters start fights, regular mudcat members are more than willing to don boxing gloves and join in. If guests are submitting posts that are designed just to irritate, annoy and be rude, for crying out loud just ignore them. Anyway, mudcat members (with real names or pseudonyms) are capable of being obnoxious and insulting to each other without the help of guests :-)

For those who really dislike the idea of guest posters you could:

Ask the site owner to get rid of the guest facillity
Leave this site and frequent ones without guest posters
Learn to ignore deliberately annoying guests

This is a very informative site with some real characters who can write well put together and witty posts, don't let annoying guest posters spoil it and don't think it would be all sweetness and light without them (and try not to put on the boxing gloves so readily ;-))
