Twotest

Twotest is the main guest account for the quickplay feature in the game. It was one of the first accounts created. Afro.Ninja originally gave the password to somebody who wanted to play a test game but never did remember who that was. And from there it just spread around. Twotest is actually the account that you log in with when you play a quickplay match but none of those stats are recorded on it. Technically speaking, there's hundreds of people that use the Twotest account daily.

The account was banned or became invalid from using the lobbies with a update that also patched some parts of the trainer that hackers used to hack the game.
