There isn't an "account" and no one has access to your "settings." A channel OP can ban you or kick you as often as they like. It's their channel. If you don't like what a channel OP does, you can either appeal to other OPs in the channel or else choose a better channel.
If you are talking about IRCOPs (network OPs), then they have more access to seeing information about your connection and can choose to ban you or kick you from the server/network itself. The only option there is to try talking to another IRCOP about it.
Anyone can see basic info about you such as /whois information, which includes things like your hostname/IP address, your Name (if set), what channels you're on, etc. You cannot prevent this from being seen.
