[2023] Multiple activation of EUIV: Domination issues

This is after buying Steam keys rather than directly from the Steam store?

If so, from what vendor(s) please?  

We have several tickets on this in our ZenDesk system, most for Gameray but one on vk.com . Neither of those vendors are listed in our authorised ones

Approved re-sellers

Hello everyone. I've been wondering for some time, who/what actually are the "approved re-sellers" that Paradox considers legitimate? Is there a list Paradox has made, which has all of them? If not, why? I'd think something like that would be... forum.paradoxplaza.com
Which is not a 100% guarantee they are unauthorised, but it is possible! I'll get Paradox to confirm it either way tonight.  

Best to lodge a support ticket at paradox.zendesk.com on that, as it will need to be dealt with by Paradox directly.
