While searching on google and navigating the web for crypto-currency subjects i see more and more the domain
bitcointalk.to,
It's a phising site that copy every single post of bitcointalk.org
If you access this website once, it could stay in your chrome/firefox history and you can access it by mistake when you want to join bitcointalk.org if you dont double check the url ....
I suggest
you install MetaMask so it will automatically block this site if you access it by mistake :
