Blacklist - Bingo Card + friends

More online bingo sites blacklisted by bingoguy. We strongly advise that everyone stay away from bingocard.com + bingolol.com + redcardbingo.com + bingo-millionaire.com. Again, several months of emails and I can't even get a response. What are these people doing? How difficult is it to answer an email. This is really frustrating. We strongly advise you to stay away from all of these sites.
