Okay, so there's a place that's taking fanfic off AO3 without permission, and if you want to get it removed then you can follow the advice on this link (also, more details about the company etc):
http://ao3org.tumblr.com/post/116311865913/fyeahcopyright-update-below-weve-been However, the only thing they've taken of mine is an Atlantis picspam and I have no idea if the rights for fanfic also cover fanart. Basically, does anyone out there know if I can ask for it to be removed? Thanks!
EDIT: I was going to complain about my artwork, but the link no longers leads to it. So, I checked their authors pages again and noted a) instead of 40 plus in the 'le' section, there's now about 25 and b) I'm not on their list. I think this means they've already removed my artwork. Possibly because it's not fic, but art, or possibly because so many AO3 people complained they've removed the ones they took from there. Not sure, but hey, it's gone. That's the good thing!! :D
