I accidentally numbered a batch of songs incorrectly so put 52 files through MusicBrainz (freshly downloaded) and put it through

Scan did all but 14 of the files so I used Lookup, a few of the files looked correct with lookup so I brushed it off and said I'd take a closer look tomorrow, but before that I wanted to renumber the files again (this time properly)

While numbering the files I noticed that a few of them were obviously wrong, so I started deleting the 14 that had been done through lookup (I was just going to redownload them) when I noticed that one of them (I forgot since I immediately deleted it and all of the other MusicBrainz touched files) had a black and white photo of naked young boys with their penises out

At the top of the image was "CREATION" in a font and in the top right was some numbers/letters

I have no idea how this happened or what exactly to report so I just laid out everything I could

The only setting I changed was toggling the rename files option
