eh, for all concerned
we obviously do not promote, encourage, or help with evadeing, if your not wanted in the channel stayout.
however, i see nothing wrong with educating someone on how bans work, this is useful information. Some times because of evaders more strict bans are set, i even have entire country extentions baned in my channel, which i've found to be nessicary, it does however restrict some inocent users from joining my channel, and those users have a right to understand why.
not knowing the exact case here. the answer to the first question as was already pointed out there are different kinds of bans, a ban can be set on an ip, or on a nick, or ident, or any combination of the 3. even partial hostnames.
for example someone could ban *!*@*.com and that would ban thousands and thousands of users no doubt. all from many different ip addresses.
sometimes i've placed bans like ?????????!?????????@* because of a specific clone script that uses random chrs in forming the nick and idents of its clones to atack a channel via proxies .. this bans anyone with a nick and an ident of 9 chrs in length .. different kinds of bans are set to combat different kinds of threts.
as for your 2nd question, how does he know who you are
there are many things that could give this away, your ident is proably it though, als your 'name' filed is visible during a whois.
i hope this has cleared things up and settled the dispute about what kind of help we will and will not provide.
