Hello. I want to start up with affiliate casino website. I don't know anyone from this niche so I'm asking here, maybe there is some Polish guy here or someone else will know

I'm from Poland and the website would be in English. I'd like to promote it on western markets. Is it legal? What's the solution? Blocking traffic from Poland, just in case or just don't give a fug? I'm poker player and when it comes to poker law - it's illegal to play online but the law is dead, everyone is playing and no one gives a single fug about it. Is it the same in this case?

Thanks.
