There are a few that are a pain in the ass, but here's the people that love boxers so much that they're willing to give us free gold, even at level 1:
People trying to start a guild!

First thing I did when I rolled my 5xShaman on Magtheridon, at level 1, was to: /1 5 guild charter signings available for 10g. Boom. 2 people came running.. signed all alts on 1, guild was formed. Dropped guild and signed the other guy's. Easiest 20g I've ever made at level 1. Looking back, I should have asked for 20g a 5x signing..
