Found this old comic series today called My Little Pony: Friendship is Betrayal. Some links:

The comic was hosted on this webcomics hosting site which seems to have other pony-related webcomics too: https://comicfury.com/search.php?query=&tags=My+Little+Pony%3A+Friendship+is+Magic
There aren't many of them at all so it shouldn't be difficult to get them backed up.
