I love the number of "wtf" comments. It's an issue, but someone needs to tell you what happened.
To be specific about what happened, Ez was DDOS'd. The reason he couldn't move was that his IP was targeted and flooded (if I understand how it works right). Oddly enough the majority of games that you'll see XXXXXX paused/unpaused the game, are ones where someone on the server you are playing is being ddos'd but not in your game, or you. Also it isn't necessarily the player who is listed as pausing the game who created the attack.
Essentially a number of games are hosted on each of rito's local servers and when someone in a game is ddos'd then all the games will have a momentary pause/unpause, and it will randomly name a player as doing it. However, at least 1 player on the server will have a disconnect and not be able to log back in until they reset the IP or the attack ends. It's an exploit that was even more common about a year ago, but is still used by people who are willing to cheat to gain LP. It's scummy and I have no idea why the fuck rito doesn't have better security to stop it.
Hope that was helpful, and sorry that someone in your game decided to ruin it. (It's important to note that it wasn't necessarily the WW though because people tend to think that it's the person listed who did it, and that's not really true).
