TheScarrletDevil24 was a mock account made by The Composer after IM STILL ALIVE had banned him for everything he had done. While The Composer actually had many alts, none of them were convincing. This one was the most convincing because it mimicked everything from the username down to the picture.
The user was quickly picked out of the crowd after it showed the edit count was off, join date was off, and the two r's were noticed in the username. The original user being mocked was TheScarletDevil24.
TheScarrletDevil24 seems to no longer exist.
