A few days ago Sean Wallace posted a link to an article that revealed Galaktika - a Hungarian magazine publishing primarily SF/F - had been pirating work. At this point it seems the extent of the piracy is undetermined. (It's been confirmed that some stories in past years were pirated, but it is not certain if all of them were.) It does appear that almost every story published in 2015 was done so without the authors or editors permission.
Frequent targets were pro-paying magazines (Asimov's, Strange Horizons, Popular Science, Playboy) and anthologies.
To share details on work that was stolen from you, please either comment on the new thread over at the Absolute Write Water Cooler (Galaktika Magazine - AWWC) or here. (You may also contact me directly if you are not comfortable sharing details in public - annagrace dot carpenter at gmail dot com)
To look and see if your story has been stolen you can check out this link : Galaktika Magazine - Bibliography Click on the Magazines link, then click on the year link next to the Galaktika heading. Each authors name in the TOC also links to a larger bibliography that will show any work by that author translated into Hungarian (including some that were published elsewhere legally).
I am currently working on simply collecting information on the situation and will post updates as they become available.
