I was wondering whether I should be worried for my account or is Steam being very generous for some reason? I received an email from Steam that I had received funds under the currency of RUB (py6) in the amount of 500. I am completely baffled by this randomness and wanting to verify its legitimacy.

Here are some images in regards to the whole thing:

I'm guessing, I got these random funds out of nowhere and Steam is just being nice I suppose.

Edit- I have sent in a ticket and hopefully they can resolve this issue. I do recall that thread linked by /u/Xiru and completely forgot how similar this issue was. Thank you everyone. I'll try and provide an update as soon as I get an response.
