join channels after u have identified for your registered nick just incase u have access on the channels you are joining to have u gaining access automated.

protecting from impersonating channel admins/ops/bots:

this will ban and kick out cloned nicks like:

this kick bans users that send u PM right after u join a channel ( within 2 seconds line 1 in the code ) and obviously u need to be opped on the channels

This will kick all banned users slightly faster since it stores in var and then kick like:

i forgot who the author was of this else i would have mentioned

This will check for bad channel on join and set ban on all channels you have access like: chanOP this saves u the trouble if they join on another of ur channels to start all over again

this will get rid of mass nick changes on channel and also will check for irccloud host and ban appropriately

Most modern updated IRCD's have all kinds of features to prevent mass joins some dont tho and those that have usually only lock channel if mass joins detected not removing mass joiners therefor this code might be some sort of solution for that part

this will scann joining nicks in channel for paterns in nicks and get rid of them
