Hi, Ante, welcome to GFY.
Did DDF Cash ever get
that bullshit with the invoices sorted out?
To refresh everyone's memory, in 2015 DDF Cash sent out an affiliate email announcing that starting in January 2016 they would no longer pay anybody automatically; supposedly if you don't remember to invoice them, you won't be paid. A snail-mail mailing address was provided for sending the invoices. Obviously that's not acceptable to US webmasters who expect to be paid without demand and aren't going to bill European programs by air mail, but when confronted about it, Paul got very hostile and dismissed all concerns as "ridiculous".
That same email made some vague demands for submission of "documents" from affiliates on a very short time scale. The documents desired were never specified, even though Paul blustered at length about how "we probably don't need" anybody who had a problem with them but would provide "provide all pertinent data to affiliates" at some future time. (That never happened.) Paul then bailed on the thread and has not been seen since on GFY.
So, sorry, Ante, but you've got some bridges to rebuild here on GFY before you will be smooth sailing to do new marketing.
