I live in south africa and 15 dollars is 290 rand so either i buy it on steam or i don't buy it ate all your thoughts
From what I could find about the issue, apparently it was a mistake, and has been corrected since then. As such, an appeal should be valid for the game on Steam. If you do decide to appeal the game ban, I really hope it goes well! (Do tell me if you get it back on Steam, I'd certainly buy it as soon as it's available)
