Pixiv 404

Posted under General

My latest upload from the artist "aaaa" (very creative name btw -.-) got a 404 from pixiv. Original source is here


After i wanted to upload it, i got this

404 => Net::HTTPNotFound for https://www.pixiv.net/ajax/fanbox/post?postId=727195 -- unhandled response

I had to use another imageboard for the upload to work. Why does the original link to the source not work?
I'm just curious about why it didn't work, because when you follow the link to the source you don't see anything.
