Thank you for your feedback! We understand your desire for increasing fanfiction in fandoms with low number of them, and we discussed the matter among our team. However, in the end, since Kaleidocsope is a multimedia challenge, we want to promote all types of fanworks for under-represented fandoms. Therefore the mod team has decided that it is important to uphold the rarity criteria for all types of fanworks. Fandoms where one type of fanwork or more exceed our rarity threshold will be accordingly considered ineligible. Thank you again for your input!
