Oh...you can see what's edited by clicking on the "Last edited by" Italicized hyperlink below the post to track changes. The reason for edit becomes obvious there I don't think it really affects anything if a 3rd person sees "imperialreign's post was edited by a mod". There won't be a ZOMG! reaction. If you want to cover up, make a minor edit to your post, it will show as "last edited by imperialreign".
