You don't need to know who reported your post, if your posts are getting deleted its probably for spam or low value on which you should be concentrate and how to avoid such reports in future.
I want to know because I am just curious and want to compare it to the reporter's post.
I know, we can appeal by clicking the button
report to admin on a personal message, but i never used it yet, I don't know how it works because there is 5 admin, and I still don't know which one should i choose.
About withdraw report to moderator button (if troublesome enough on page) maybe better to put it on the personal message place.
