There is not directly link to the source but is a compilation mantained by @chtkghk on twitter. Here is his/her statement:
This torrent is an archived collection of all known works by the artist that goes by -8, minus8, chtkghk8, or minuspal.
Since the 2000s minus8 has been a highly skilled yet elusive and reclusive artist, randomly appearing on websites such as Deviantart, Newgrounds, 4chan, Pixiv, Tumblr, etc and uploading hundreds of works then suddenly deleting his accounts and everything that was shared. This collection was originally created with his permission to maintain and preserve his works for posterity and for his audience to enjoy.
For years, out of admiration for minus8's work, I've added music tracks and audio to dozens of his gifs and animations. I've converted many of his Flash-based .swf animations to .mp4 format and tried to present his works in the highest quality. I've spent years saving and spreading around his content on the internet since the 2000s. It's almost impossible at this point for me to delineate where my own contributions to his works begin and end.
I myself am a professional Japanese and Korean translator, interpretor, and writer. Doing hentai translations, writing comics, commissioning, editing, and sharing NSFW art and animations are some of my hobbies.
