They don't want to pay. That's all in this case.

I made my first ever sale for them a couple of weeks ago and I thought I had pulled all links to them, lol (cautionary measure - I will start promoting them again if Ondrej is given the all clear).

They are still making money, but not paying affiliates and not replying to emails.

Ondrej back now, but they are still NOT paying affiliates.

I guess it will require a little more patience...
Got an email end of December that "in January the payments will start to be scheduled", however silence from that time unfortunately...

I guess that if they would plan to NOT PAY, they wouldn't even bother with sending email...

So they were cleared (again)?

Or that is trick to get you keep sending traffic :upsidedow

Finally I've received money from them in January, but to be honest I am not sure if it's not risky to continue promoting them. Although as i see they have new, fresh unique content now. It's tempting a little...

yes, money received.
However rebills disappeared last year, and new sales happen not that often

I have an unpaid invoice from them from mid 2020, and just emailed Ondrej for updates about CzechCash and this invoice.
We still love the products and promoting them, but don't really dare to put in more work until things are getting better. My unpaid invoice is around 1200 USD, but on thr two accounts we have with them we have around 5k since last invoice sent [--> wild guess.]

Yep. When I looked at their offerings, my "dubious consent red flag" went up.
