Honestly, this isn't even the worst shitlordery I've seen in the publishing world, just a variety that I feel safe in calling out.
Edited to add, 6/26/2014 at 6:24 p.m.: I got the following update from Duotrope: "We have been in direct contact with the editor, and their policy is that they pay sometimes, depending on the author's experience. As such, we have edited the listing to reflect that the market pays occasionally."
I'm glad Duotrope has updated the listing. As far as I'm concerned, this is almost worse on OMNI Reboot's part: "Fuck you, beginning authors. We'll take your stuff for free."
As a matter of policy, I never submit to "pays occasionally" publications, either.
