I couldn't find anywhere to post about this: in just the last couple of months several cafes have their web filter banning Dynasty Reader for sex/porn (it's always the same message).
Just a note: As mysteriously and suddenly as it showed up, the filter for dynasty reader is now gone.* I understood better why Pixiv is often filtered where DeviantArt is not, because DA has offered up a policy. It is still troubling, given Pixiv is literally many good Japanese artists' only home on the web.
But for me, personally, the problem went away. I don't know precisely when, because in this coffee shop, I had given up on dynasty-scans.com weeks ago.
