@hexaheximal @icedquinn blobcats are mostly unlicensed...
Misskey.io people once contacted the origin discord servers and they claim that their creations fall under the same license which google used to publish their blob emojis. But im not sure which discrod (i think called something meow), but keep in mind that they have their origin out of two discord servers and most of the blobcats are done by people unlicensed
