Dijana name as an assistant producer would appeared only on the Interviews videos
I'll simplify it for you. Lloyd Evans is a bullshit artist. He likes to assign people important sounding job titles in order to make it seem like he's running a fine tuned business, with the most grandoise titles fashioned for himself. He did it for JLE Translation Services and JW Survey. Even when he was mowing lawns in Wilmslow, "landscaper" probably wouldn't do. In all likelihood he called himself the Director of Operations or some shit like that even though there were only one or two employees including himself.
With regards to Dijana and her "co-producer" credit, I think you cracked the code on that one. On the interview requests, when she forwarded them to Lloyd and he accepted, she got the producer credit. It means absolutely nothing in the real world and she'd be acting the fool to include that on her CV. She doesn't "work" for Ipsilon Media in the traditional sense. Never has. She has never shown much interest in Lloyd's activism grift except when it came time to go whale watching in Vancouver and Australia.
For some unknown reason she has dropped the pretense of prepping the interviews and an unpaid volunteer has been "hired" in her stead. She pulls a salary from him in lieu of court sanctioned child support. So when he speaks of "paying wages" to Dijana, it's child support. It's either that or she gets nothing and he swears up and down to the court that he's in poverty. This is how dead beat fathers operate.
