Is it ok to tag a circle/group as an artist and just put a _(group) or _(circle) suffix? Generally artists that make doujinshis or artwork sets work on groups and oftenly we don't know exactly the artist(s) name(s).
But I don't see people tagging that way, often artists that are on a group/circle are just tagged as unknown_artist, unfortunately. So is it ok to tag an artist circle/group with a _(group/circle) suffix and put on the artist category?
