Don't forget the most important part: why they got banned.
Basically, in the wake of the mass DMCA strike last year, MD's staff has taken a more hard-line approach to groups making money off of scanslation. Thing is, what publishers hate even more than piracy is bootlegging. And permanently paywalling chapters counts as such. PLus, MD's staff doesn't like that groups like Asmodeus bait people here by only ever uploading a few chapters here and there, and keeping the rest behind their paywalls.
Asmo got warned about doing this, but they doubled-down on it, so the group as a whole got the boot and their uploads were purged because they don't want to attract the publisher's attention. Again.
