Based on ircu, Nefarious has features from various IRCds
(Asuka, Bahamut, UnrealIRCd, and UltimateIRCd) with the
intent of adding needed features to ircu without becoming too
bloated or subject to anti-user behaviors. Most features can be
activated or deactivated in the config file. Nefarious includes
optional support for RBL-based blocking or marking, fakehosts,
accounts, login-on-connect, half-ops, ban exceptions, mIRC
color filtering chan-mode, network-wide bans (g-lines), and
much more.
