Background verification for govt exams

Last year I linked my PAN card and account details to an online poker website PokerSaint. I want to know if this is going to be a problem in background checks in govt exams (UPSC or other)? Do they even check this kind of informations? Do I have to delete my account details and log in id in that website? And also, is it going to affect if I apply for F1 visa (student education) for foreign countries?
