Well I looked around and there are some unlicensed manga sites that are very popular and have used AS for years, like http://manga.bleachexile.com/ (Alexa 729) http://www.mangafox.com/ (Alexa 6000) http://onemanga.com/ (Alexa 169). I'm guessing they don't care... which is surprising, since there are numerous supposed violations by these sites.
Many of those copyrights are in Japan, many of them never follow up or care about people copying their work outside of Japan, most can't afford taking a case outside of Japan either. Peace,
