DreamOnPvP was the old name of his old Minecraft account DreamXD. The earliest activity I could find was his first Hypixel log in back in November 2013, using plancke.io. He's trying to phase this name out though, I mentioned this on the thread a while ago.
Looked through that River Phoenix profile. It's still active shockingly. Seems to be owned by the kid in the black shirt from the video. Found these pictures that could have Dream in them:
Someone from that group chat posted his name on their CuriousCat page, more information on Page 179. I don't know the connection, maybe another coach?
May 10, 2016. I'll be archiving it as well.
Not to shit up the thread, but this is MASSIVE. Ladies and gentlemen, it has been confirmed Dream was fat, with more photos.
Meet Andrew Rife. (Archive)
Seems innocent enough, right. That's until you look at the intro section.
Is that Clayton?
Yes, yes it is. This is fucking crazy...
The thought of the burner account that posted the thread being someone in that chat seeking attention or something did come up in my mind while I was writing my post, I wouldn't be surprised if that was the case.
I did some digging on that thread. Most of the people on the list of Twitter accounts changed their usernames (or deactivated possibly).
The person who intrigued me the most is @wotsthisthen. Their account is private, but they have a CuriousCat link in their bio. (Archive). They seem to lurk...
Something I've always wondered is where these people get all the shit they have from. There's a photo on that thread that supposedly is with Karl Jacobs, Sapnap, and Dream.
Since we can't see the full photo it's hard to be 100% sure, but there's a photo that looks almost exactly like that one...
