(I was thinking of waiting until I/we had this complete, but since this uses a feature that will likely be removed soon, I am going to add what little progress I made and later make replies going forward. You can add what you know, too.)
Real quick notes: ARG = Alternate Reality Game. Essentially, a side-story that involves the community working together, traversing a large amount of decryption to find out one ultimate goal. There's much better explanations, but I don't really have the time. Just look it up on Wikipedia or somethin'.
So, y'all know The Faucet, right? Under the Wiki Community tab? No one's really gone into it, but it's suspicious stuff. So far, I've only really seen people go on the surface of it. It's probably been solved fully before, but I haven't seen a full explanation, so i'mma just throw it out there.
At the bottom, you guys know the magic numbers?

Looking at this, it's quite obvious it's a ROBLOX ID (after all, ROBLOX themselves have done it before, but it's actually a Player ID, which is quite unlike a lot of ID usage before. The user has a Twitter page linked, which leads to a Gyazo image. This is as far as I've gone so far. Since ROBLOX removed the ability to link your Twitch or Facebook (and maybe YouTube, I don't remember), it's likely they'll remove Twitter aswell soon, thus the rush. However testing the Gyazo shows that you won't have to modify it with any image editing software i.e. GIMP, messing around with contrast and checking colors et cetera. Typical ARGs usually involve a different form of modification, i.e. compressing it with WinRAR or 7zip and then changing it to another format (or just looking directly). I'll look more into this later.
Someone probably has already solved all this and is gonna explain the rest, so good hopes lol
