A link with all info here, including how to request they take your stories down. Link to contact the community itself here.
Basically, an e-book community is taking our stories from AO3 and FFN and posting them on their site. According to some intel, people are being charged to read these works (and I know I'm not getting any money). Two pages of my fic were listed under both of my psueds, so be sure to check for yourself.
Please boost the signal on this!
