It seems like this person who owns GameA is deeply worried about some satirical criticism being posted on YouTube.
How does this person dare to say anyone who criticizes him is a liar?
Look at the pornography he posts and also the off-topic spam while pretending to be someone from India. Believe me when I say, I know this coward very well, before insulting others, the game itself, the developers of Duel Links or any other person across the internet, this criminal is always taking the name of Russians, Germans, Arabs, Indians. His job is pretty much simple, he needs to boycott companies that doesn't belong to huge multinational corporations; that's why he has created this website, just to manipulate the public's perception about this game, to damage the public image of Duel Links. Masonry doesn't do it only to Japanese companies, masonry has created popular internet rants like "XBOX has no games", so they can boycott a competitor in the market and push the sales of PS4 at the same time. It's an organization full of racketeers.
Having said this, in this website you will only find pornography and other graphically offensive material, slander against this game, insults against other players and as I previously mentioned, off-topic spams as well.
GameA should be closed because it's a domain created by criminals, managed by criminals and has been created with malicious intend. A website like this cannot represent Duel Links nor take its name.
