So maybe don't share those aspects of your real life with other people in such a forum when those same people may or may not breach your trust in them not to divulge it further? That which you publicly disclose may invalidate any expectation of privacy you may have. I can't put something out into the world and then claim an expectation of privacy after the fact, that's not how the world works. You made a choice to disclose non-CF aspects of your life in a chat. Maybe you did so because you believed there was an implicit, or even an explicit, expectation of privacy therein with the other people in the chat, but either there was none, or if there was it was breached.

The fault lay not with the Imms, no matter how you want to spin it otherwise. It is solely with the person who disclosed it. If Imms receive a file which says here you go, proof of cheating, they will look into it, as they should. Whether that file contains other things as well is irrelevant, and how would the Imms know what the file contained fully until they looked? Should the Imms have asked how the guy came to be in possession of the file before looking at it? Something tells me he was a willing and accepted participant, he didn't hack a computer and steal it. You just trusted someone who ultimately breached that trust.

The person who discloses your private conversations with them is the one who breached your trust, not the third party to whom it was disclosed. Shaapa (I think that is who it was) could have edited it out to show only CF related things, he did not. He could have never shared it at all, but he did. He could have warned the Imms about extraneous non-CF content, but I am doubting he even did that.

It's fine if you want to feel slighted by the Imms for looking at it, but I'd say your anger is misplaced. And Rob is correct, the Imms have a duty to look into allegations of cheating, not to do so would be a greater breach of trust between the Imms and the player base then the breach you perceive.
