Did you ever test DNSCrypt?
Oh my God, I never tinker with DNS seriously before. Thank you very much for this.
Credit is a given, but the reason they like/ed batoto was because their release delays were respected and the releases weren't altered for the sites convenience. Not sure how mangadex is setup, but it looks like everyone and their mother can upload anything as they please. No group is going to endorse that practice as it's only catering to readers, which is nothing like batoto.
Mangadex have discord server, if you want to give some inputs, you might want to join it.
