I have enabled a VPN with a Singapore IP address and tried to access the site, but I also had no luck. So, I don't think it's a problem with Cloudflare. It looks like the freebitcoin team has started purposely blocking access to the site only for IP addresses from that region. I don't remember if Singapore was mentioned as a banned jurisdiction in the updated ToS or not, but I can't check it now as I can't find a link to the ToS where it used to be on the main page.
Same for me, I tried to connect to the website through a VPN with several Singaporean Ip adresses and none of them have worked. I got a page from Cloudfare saying I've been blocked with the text below, so I guess an attack originated from this country has recently happened and Cloudfare is temporarily blocking all connections from this country.
