@Kayriel you make a big fuss about how aggregator sites do illegal shit by simply posting the group's uploads somewhere else. If you actually bothered to think about it, ANY site that uploads things like this is a file sharing site - which is illegal. Aside from that technical argument, I've had to look into the legalities of scanlating, as I'm a member of a handful of groups, and its ALL illegal, whether the manga is licensed or not.
In other words, bitching about another site posting a group's works, bc the group is having some childish feud and boycott with one site, is akin to you yelling at one pirate crew for stealing from another pirate ship.
The groups can't do shit about aggregator sites, and they know it. And you gotta remember - there is no "official" site to post manga to. So even mangadex is, you guessed it - just another aggregator.
TL;DR - you're bitching is invalid and annoying, so shut up.
