Don't Leave + The Deep Forums (Double creepypasta)

Introduction
Okay, I don't usually have these problems. In fact, they never happened. But this is terrifying. To me, at least. This is over the course of a couple years. (I think, I can't remember clearly now)

2010
I joined ROBLOX on this date, but never knew about the forums until 2012. Yet, strange things happened before I even knew about the forums. Yes, this is called the Deep Forums, but there are a lot of important stuff before the forum part."May 21st, 2012"
