Reply by Wikia Staff regarding Checkuser:
"Hello FastLizard4, It would indeed appear that the users you inquired about, while currently do not, did at the time of both their account creation on the Metroid Wiki, contain the same IP address. Action on the matter is strictly up to the bureaucrats of that wiki however, though it is standard procedure to block all but one of the socking accounts. As for your other question regarding the AWB, I could not say; SourceForge has been having issues with their database as far as we can tell. It may prove more helpful to contact an administrator of Wikipedia rather than Wikia. Kind regards, Angela"
