Like someone has suggested, all it takes is for someone to log out and they would be able to see your post, so implementing such a feature is a waste of time if takes literally no effort to circumvent.
@carra
Current rules do not allow uploading of any raws, defined as publication in the original language, regardless of whether it is out of print or not.
Scanlations based on it would be fine though.
We plan on introducing reviews at some point, but the way ratings work won't change. We added the Bayesian average to mitigate the effect of extreme votes already.
The reason we don't link to group sites directly is because it will be a massive administrative burden to make sure that those links aren't dead in the long term. It is highly unlikely that M+ would die (plus they are also a free official source), which is why we only link to them.
@Shiggle
I wasn't aware about Hati.
In any case, we have all their previously uploaded chapters in the archives, so if they want them restored, all they have to do is ask.
Speaking of Doki Fansubs...😀
A lot of the groups which left have come back in one form or another. Personally I prefer to let things stay as they are. Groups know that the door is always open for their return.
