It happens when you repost.
Thanks to the anon that made these.
I simply reupload nice pictures now and then to remind anons not to give into satanic hate - the undoing of every human project ever, including /pol/ and /cbts/. I find it amusing how it was declared "message from Q!" in one of the past breads, but the important thing is message itself, not the messenger.
This filename thing happens because I saved those images using their hash as the filename.
