No matter how you spin it, it is policing content. When MD started out there was no such rules. Scanlation itself, aside from trying to curve it into helping official releases, has been at its core a free field for scanlators. You upload a chapter on 4chan, you don't expect anyone forcing you to remove a TL page. Only places you get censored is sites like KissManga and those other aggregators who will purposely remove credit pages and anything they deem not fit. Guess what that almost sound like? This second rule.
I would like to think MD's best selling point is 1) no ads and 2) it does not stoop as low as those other aggregators. However as more days pass, your moderation mindset starts to skew toward removing certain things to keep the place peaceful. If a scanlator is problematic, so what? Let them be hated, let them be flamed, let the chapter's discussion be full of needless salt. There's a block feature for people AND groups, what more can you ask for? There is no need to moderate everything being said, neither scanlators' or readers'. If a reader is insulted by something, then I feel like it is a problem on their side and not on the moderation site. They need to learn humans are shitty and can be provoking, religiously and whatnot. Crying to the mod for something triggering them online is not a solution. I have shit I get mad over as well, but I also learned to leave those people be or rally supporters for my cause in a forum and take action against them, if it is an issue I deeply care about. Why is there even a need to be moderating things that can be offensive? Especially in these scanlator's notes, which is coming from the people who brought the manga to us. They literally spent their time doing the manga, and yet they can't have the freedom to express what they care about?
Or perhaps, consider getting a full moderation team if you guys are so helpless and still wanna moderate every single things being said. Imo the internet is just a place you can't moderate everything. Making an effort is good, but trying to completely moderate everyone will just result in them moving away. If someone else were to build a reader site and promise it for being free of moderation while using similar system to MD, you will see how it will basically stabs MD in the chest. Hopefully you guys are making logical decisions.
