I remember hearing about Dr. Pong early on and never followed up on it, so I decided to do it when I saw a thread on 4chan mention it.

Dr. Pong is a restaurant/ping pong joint at least tangentially related to Alefantis, as they were both involved in transforming the Dupont tunnels into an "art space", according to this archived document: http://archive.is/JoY0a (Scroll to the very bottom.) I seem to remember another connection along the way, but can't remember, so if someone could point that out (if it exists), that would be just swell.

I went to the Dr. Pong website (archive found here) and clicked around. Their pages have illustrations, the first two of which seem innocuous enough. It's a Lucha Libre fighter and a gentleman smoking a pipe with a three (?) leaf clover on his hat. The others, however, are pretty odd. Individually on each:

An infant, a boy, a goat, and a hotdog.

That's two pages with children, a code for CP, and a goat, which is featured heavily in Satanic rituals.

Rather bizarre for a restaurant/ping pong place which, by the way, does not look very hospitable, as shown on their home page I linked earlier.

Under the Linken tab, one of the related websites is GoodandPlenty.de, archive link here. If you visit there, you'll see an animated gif of a busty young lady dancing in front of photography lights (flashing on and off), with another gif of a hotdog and burger alternating behind her. There is also a link that says "Click HERE for more super hot shit," which takes you to this youtube channel: https://www.youtube.com/user/SchweinpegResearch, which talks about data compression. The second video (which is NSFW as it contains a pornographic image) is titled ["The Use of Advanced Data Compression..."] (https://www.youtube.com/watch?v=q-fpmy_wJPw)) is pretty weird, as it shows an (ironically) poorly compressed video of two guys -- one in sunglasses -- livestreaming while explaining how to compress files. At a a few points a pornographic woman shows up, as well as a picture of what appears to be a hotdog in a bottle.

This is as far as I've gotten. If anyone else has advanced this line of investigation, it'd be appreciated if you linked to it.

There are quite a few links on the Linken page, so have it at it lads.

NOTE: I would just ask that if you DO find anything, please archive via https://archive.is (it's fast and efficient) and also provide links in your replies. We want proof or something close to it. If you say you found something, show us what you found! Please don't be lazy, as otherwise you're just giving us the chore of chasing down your supposed lead. And finally, if you don't have proof of it, don't claim it as fact. I've noticed a lot of outlandish (i.e. bizarre and unfounded) claims around here recently that I fear are discrediting the investigation. Beware the slide.
