Regular nicks we generally trust and have recently positively interacted with are Tuxavant, gmaxwell, jgarzik, LobsterMan, nameless, OneFixt, phantomcircuit, phungus. Nicks can be faked so it is imperative you use some alternate means of authentication when any trust is required when dealing with people on IRC.
