All the typos in their news post lead to this site, but I got no time to further dive into this puzzle atm.
EDIT:
Eh, I'm an idiot, you just have to type in the rest of the hidden message, from there on out it goes further... bet someone on reddit or something similar has already solved it.

I actually looked on reddit and I guess I found the password for something else there that is a bit different from the password I needed to use on the site initially. Albeit I am not entirely sure how to proceed from there. Colour me intrigued.

I got one email in russian I assume. Should I expect another email with the key or is in one of the links in the email I got?

Dear friends, the event "Key for subscription" has come to the end. You can not get the game for free anymore. Everyone who subscribed to this moment, received their keys.
👾 If you have subscribed, but you have not received anything, check the Spam folder. If there is nothing, contact us via PM on Facebook and let us know from what email and when exactly you have subscribed.
👾 To everyone who got the broken key, and who asked for a replacement, we have already sent a new one. If you asked for a replacement, but have not received a response so far, check the Spam folder. If there is nothing, drop a message to us via PM on Facebook.
👾If you have received the broken key and for some reason have not yet ask about replacement, hurry up to write us on the same email as the broken key came from.
Don't worry if you did not manage to take part. A lot of great news awaits you in the nearest future. So keep the ears on the crown and wait for new emails from us.
