Basically I'm wanting to set up a spam filter so if someone is trying to identify for a channel, if it can alert if the non-founder tries to hack a channel. It doesn't need an action, just a notice seen by the netadmins in their logs.
We don't have this because it would allow easy spying.
You can use action warn, but this will send a message to the sender that a spamfilter got trigged... for precisely the reason I just mentioned above :P
Understandable, if it's a possible filter, I'd be adding the specific channel cause one guy has had someone nail his channel already and he's wanting to figure out who so I would set it up to the specific channel to try and catch whoever is hacking into users channels. I can see who's listed as channel owner and successor so if whoever isn't one of those two, he's caught. How could I set up the channel without the ircd looking at the # as a comment out? or does it matter?
To be honest in my opinion it is the Channel Founder/Owner's responsibility to keep his/her channel secure and not that of the IRCops. If his/her channel has been hacked/cracked (i doubt hacked) then he/she obviously cant be using that strong a password in the first place and should perhaps try a stronger password.
An example of a stronger password would be one containing letters, numbers and/or puntuation with a mixture of upper and lower case.
The other point is this person should also be very careful who he/she trusts or maybe even to not trust anyone enough to give them +o in the channel.
You can't set a spamfilter specifically for a single target, and by default, /cs and /chanserv are excluded from spamfilter checking anyway.
If you have anope, you could just switch on the logchannel option, which will cause anope to log everything to a channel of your choice (usually you want to pick a channel restricted to ircops or something). Including IDENTIFYs to ChanServ (both failed and not). Or, if your version is recent enough, remove cs_identify from the core modules to disable /cs identify altogether (I have to ask, what the bloody heck is the point in that thing?!).
The alias block has an option as to whether it is affected by the spamfilter. Not sure if this includes filters added by /spamfilter but im pretty sure it includes spamfilter blockas as well.
If you was to add spamfilter blocks to accept /cs and /chanserv for example you would also make sure they are affected by the spamfilter.
