So there is a chance it will continue to work as long as the buyer wants it to, i just hope is not someone like say the owners of mangafox who buy it xD
Well, the site might "work", but don't be surprised if you see a shoe store or something the next time you visit.
They're buying just the box (Bato.to), not what's inside of it (all the manga, forums, comments, databases, etc).
Either way, I suggest to visit the site with caution after the deadline - you never know what kind of people end up buying it.
