I often see users confused about "disinterest" being the reason an Approver skipped over their post (mainly in the Upload Feedback Thread). I think removing the "disinterest" message in the post moderation history will help make things clearer for them. Since it essentially means no reason was given, then just stating it was disapproved or replacing the message with "no reason given" would be more straightforward ways to express this. We removed the "X did not like the post enough to approve it" message for the same reason, so I think it would be reasonable to change this message as well.
As I was writing this, I also realized that saying "post #xxxxxx was disapproved" makes it sound like the Approver is actively against the post being approved even though they could have a more lukewarm opinion about it and just not like it enough. Changing it to "post #xxxxxx was not approved" would keep the connotation neutral and likely reduce the number of misunderstandings.
