Today being Friday, I went to read the ch.155 and found it blocked from accesss through a website. Yep, it's time for pay our dues. Whiteout Scans have already posted a statement. The scanlators appear to be interested in continuing, but what am I to do if I want raws? I suppose the only way is to reverse-engineer the app's network protocol.
UPDATE: Whiteout report that all the images in the app directory are unencrypted, so "Slapping the JPG extension onto the file names is all it takes to make the files legible again!".
