Banning scripts is still very common. Ban mostly by a common identd that's set up by default by the client. The bans come in place not because they simply use a script but because the script advertises and disrupts the channel. Quit messages and "version notices" can get quite excessive from these scripts. Sure, they might look cool to the author, but not to everyone else.
As to the original question, I don't see why it couldn't be done, but also don't see why anyone here would have an interest in helping you circumvent the security of any given IRC server. We might not agree with their reasons, but we don't have to, it's their server and they have the right to refuse our connections for ANY reason they can come up with.
