Now this is a myth that occurred only a month ago, to yours truly, I'll share my experience. In a relatively new game I was testing just for the heck of it. A guest joined the server "Guest 666", he was quiet for a wile. So the server began to ignore him, just sat in amazement that we are seeing Guest 666, thought it was luck, until, he spoke to us. He began saying normal things like "Hi, I'm Guest!" or "We should play", but later he evolved to more sinister things like "I didn't want to kill him" and other completely random things the server didn't understand. Guest left the server, and after he left, the server inverted its colors, black turned to white, green to red, and eerie music began to play, and at the same time, we all disconnected. None of the other players in the server have responded to me, much less even been online since then, say me and one other. I have photographic proof of all of this I will post later on the group if you would like to join and see.
