I'm sure this has come up before, but the search results didn't manage to show anything relevant so here goes.
In the past, I've been able to download chapters/volumes from Bato.to - was this changed recently? I'm using stuff like WGET and JDownloader to download the content I want and read it with the applications I want to use. While I understand that you guys rely on advertisementrupees to stay afloat, I also don't think it would hurt your income to allow these unconventional download methods (Besides, who can even see the ads nowadays, with adblock extensions/plug-ins/edited hosts file... Hell, even MS Edge will support this stuff) and would get you a lof of good will from those that don't wanna read comics behind a computer.
Unless this draws too much heat from a legal standpoint, in which case I can understand completely.
