No.

People tend to register with services, leaving behind their mail addresses or other data we don't want to have and don't want to be in charge of.

Ok. Just use a bot that gives you op or whatever you need. Authentication towards the bot is possible through client certs or a multitude of different means.

First you need to create one:

openssl req -newkey rsa:4096 -days 365 -x509 -keyout irssi.key -out irssi.crt -nodes -subj "/CN=yournick"

Next you need to configure your client to use it. If you use irssi, add the following options to the darkfasel server config:

servers = (
  […]
  {
    […]
    ssl_cert = "~/irssi.crt";
    ssl_pkey = "~/irssi.key";
  }
)

Don't give away your private key!

Some blafasel users weren't too happy with the missing security features of blafasel, so they forked a darkfasel net.
