Not much to add, almost all has been said, and I don't have enough energy to tell everything that I consider good or wrong with the actual system.
Just wanted to ask a question:
Is this a site by scanlators and for scanlators, or a site by scanlators and for readers?
Difference? Well, if you prioritize scanlators you have, up to some extent, preference over big scanlation groups, or scanlation groups that have supported Mangadex for a long-term.
On the contrary, if you priotize readers, then any hooligan can form a group and call himself a scanlation group, and has the ipso-facto right to shit on groups that have been doing their part for a long time.
Does this mean moderating sniping? Not really, but giving full rights to any newcomer and/or anonymous, in a drama-involved scene like this seems, at least, a risky decision.
