Not sure what happened to Binance Playbread.com, but it seems like they might have shut it down or rebranded. Haven't seen any updates lately. Maybe someone else has more info or a new link?
At least there is an official notification from Binance if it is true that Binance Playbread.com is their site, so as long as Binance has not issued an official notification, it can be said that it is a fake site that uses the name of Binance as their supporter.
I agree with you that there is no statement on their social media that they are working with gambling sites, moreover from most people regarding Binance as a large and trusted trading site, it is very strange if Binance launches a gambling site or works with a gambling site, of course it must be watched out for with this or can find out on their social media to see the truth, is it true that Binance is working together or not !!
