Following the version 1.01, 1.50b, 1.52 / 1.60 and 1.62 ports of the PS4 Playground and Sony's recent PS4 Firmware 4.74 update, today @HydrogenNGU announced on Twitter that Sony appears to be blocking e✘treme-Modding's PS4 Playground from 1.76 Firmware Web Browsers. 
He also reports that AzuraMenu located at AzuraMenu.com is not blocked as of yet, but whether Sony is on another rampage against PlayStation 4 homebrew developers remains to be seen.
Below are some of the recent tweets, and if anyone here is still on 1.76 OFW who can also confirm this rumor that e✘treme-Modding's PS4 Playground is blocked let us know in the comments.
It's confirmed to be working when using a proxy, with several links HERE for those interested.
Cheers to @B7U3 C50SS, @ombus and @twostepmic for passing word along in the PSXHAX Shoutbox!
