I stumbled upon Educational manga about a mad scientist which is a manga identification request on this site and from the look of it, I think it's allowed on this site (upvoted and not closed).
I found What do we think about story identification? and Are comic identifications on topic? which seems to conclude that yes, identification request is on-topic.
Anime & Manga Stack Exchange is maintaining a meta post What identification requests are acceptable here? Otherwise, where else can I possibly get helped with it? in which it provides alternative sites such as SE sister sites, or even external sites.
Considering that this site also looks like a suitable alternative site... now, before opening a possibility of flood gate of low-quality manga ID questions that have plagued Anime.SE:
- Is this site open for being mentioned as an alternative site on a comment?
- If yes, is this site also open to be listed on the said meta post?
(Of course, we'll try our best to provide recommended guidance before suggesting them to post on this site)
