Please refrain from bringing up topics whose only apparent purpose is to cause controversy, arguments and/or anger, as per Rule #0. And please do not derail discussion of the collab by discussing a character, as per Rule #6. @Background Pony #0AC8
The reason for the removal of Luftkrieg is that their presence was noticed late by the organizers. Upon examination it was determined that it was in violation of rule #13 of the collab submissions. They were included in the previous collab as the organizers weren't aware of the character's status at the time.
Anon Filly happened to be in the same image, hence was also not included. If the artist wishes, they could upload a solo Anon Filly version of the upload, and we will amend the collab image to include them.
