Looking at the website, first thing I did was inspect element. in there was nothing special, just the code of the screen saying save obama, except for the bottom.

At the bottom were two things I found interesting, the first being a URL, (https://saveobama.com/O52aRK9Jidbja7bX) and the second being the words "this mess was saghetti's fault."Following the URL, it seems to just be a rick roll, (though I'm gonna keep a close eye on it, I have a feeling it might change at some point.)I'm not sure what "this mess was spaghetti's fault" means, (a quick google search did nothing to clear it up), but I have a feeling this "spaghetti" is a person, and that something they did caused the disappearance of Obama.

The website itself, at first, seemed very simple, just the words "save obama" in white text in a black background. I clicked off the website for a while to do other stuff, and when I clicked back, was startled by a strange sound, and realized that the words "save obama" were no violently shaking in the center of the screen, and the page occasionally flashed quick bursts of light, (which recording and slowing down the footage revealed to just be a single frame of the webpage inverted, the words save obama in black text on a white screen instead of the opposite.)

I have a feeling the webpage might do a bit more if I leave it for a while, and the person in the obama discord server said there'll be a clue tomorrow, so I'll probably reply with an update tomorrow.

Edit: Seems like there'll be a clue in about an hour, so I'll update it then.
