If you check the deleted image page there should be a link to the related thread and see which mod deleted the image.
I just wanted to clarify that I've received a message from another user saying that non-mods don't get the link at the end of this part. I thought that, since they can see the same deleted image page, they had the link. It makes sense why it isn't included, given many of the heated attacks against management as a whole and stalking of specific mods when users find out who deleted their images.
In that case, I wouldn't mind continuing to have threads like this posted, and I'm fine answering messages about why an image has been deleted, just as long as no mod is targeted out of anger. I understand that it's frustrating to have an image deleted and not know quite why, so I don't want to demonize every user that has this question or ignore messages asking about this. Not that there aren't some insubordinate militants who need to conform to the authority instituted for the benefit of the aristocracy - can I get an amen? =P
