Hail Satan is a website on the Deep Web. The main page shows a poem about worshipping Satan, and an image of a Pentagram.
It should be noted, that this site is bugged, and can show the key cue on the homepage, even though, the code is really on a subpage, therefore you only need to check the frontpage for a key cue, and only if that site shows one, you need to check all the sub pages.
Sometimes, a red room key can be found:
-in the "pictures" subpage, by clicking any picture, loads a code at the top of the page or as a file on the desktop
-in the "videos" subpage, by clicking on any video, or rather the message saying you can't view it, which then loads a code at the top of the page or as a file on the desktop
-in the "FAQ" subpage, at the bottom left corner
-in the "Members" subpage, by clicking any member, loads a code at the top of the page or as a file on the desktop
-in the "Links" subpage, at the bottom of the page below "under construction".
-in the "Contact" subpage, by clicking on the letters "fb" in the red line of the .ann link.
