Looks like they usually upload in Thai, that's probably why a sudden English release needs approval, the unavailable chapters thing certainly is annoying, but I understand why they do it, the chapter spammers that went rampart last year where twice as annoying, as they'd upload dozens of fake chapters trying to promote their own website, website that, mind you, was filled to the brim with spyware and ads, the day or so of an unavailable chapter is worth the trade off IMO, as it is by far the lesser of two evils.
