MarkoH01: This normally is not even possible since you won't be able to click on any blocked game at all. The only reason this is possibnle in this case is because the discounted offers were given an e-mail notice no matter if blocked or not. In all other cases the gamecard will not be shown at all so you won't be able to click on anything and so it copuld not redirect you to general pages therefore confusing you.
PaterAlf: It often is possible to click on the games, because of the release threads or news threads for promos that include links to the gamecards.
Ah - o.k. I did not think of this possibility and since those newsthreads are available for everybody and it is possible to switch languages for everybody this in fact might happen. So I change my point of view and agree to what you guys suggested GOG to do :)
