Screamer Forums and Screamer gallery have returned.
The Screamer Forums will likely remain read only unless it's known that it will be active, since forums in general are kind of dead because of Discord.
Thankful
Thankful, aka "Hello", was a screamer webpage hosted on Neocities.
When entering the site, a notice would tell you that the site requires autoplay for it to work correctly. When you proceed after turning on audio, you were then taken to another page, titled thankful, which played a screamer of an edited face which is believed to have been created by the "unexpected.exe" instagram account (yet the original post has not been found) inverting in color rapidly.
The site has undergone many changes and revisions before it was shut down.
