Ummm, maybe I missed something, but why do completely random user accounts list a user group flag called "poweruser"? This isn't specific to any wiki's, it's completely random and there's no description or mention of any such flag on Special:ListGroupRights, neither do the rights logs even show such rights were granted in the first place. I didn't see this yesterday, and only just saw it today, so I'm curious about what this is all about.

Examples: Can someone actually explain what this is all about? o.O
 * On Narutopedia: Seelentau is listed as being a "poweruser".
 * On TES Wiki: Atvelonis and Cheatcodechamp are listed as a "poweruser".
 * On Homeworld Wiki: Both myself and Niirfa-sa are listed as being a "poweruser".
