Am I hallucinating or has a post with links to some relevant comments by RidiculousHat just disappeared? 
Great job, ‘moderators’! 
In any case, here it is from my tab history:
https://www.reddit.com/r/hearthstone/comments/1e59e5l/soooo_shop_is_still_closed_for_russia_and_belarus/
and further links from that comment.
Mind you, it’s an official source, so I think it could be useful if it is linked here.
