@Leah Was it authorised by Impatient Scans, though? The release is theirs, but the upload was in name of a group with the "s" and the user, with the same nick, registered today. This looks deliberate to circumvent the group's member-only upload restriction.
Impatient Scans may be coming back, indeed, though. PlumJucie herself released
Skip Beat! and
Namaikizakari a few minutes later.
Then again, their group's description still says they don't allow rehosting here. And their old releases aren't back.
So, we'll probably have to wait for some clarification.
If all it took for them to walk back on their "we walk out" policy relative to MDex was that one release by Evil Twin, they perhaps might want to change their name to Snowflake Scans. But whatever, welcome back and hope the rest of the Yona chapters come back, too.
