 /*
 Checkuser staleness checker, written by Writ Keeper and Tamzin. Checks contribs, deleted contribs, and user creation date, and determines whether the account has activity past the 90-day checkuser staleness mark.
 Runs on SPI case pages, i.e. subpages of [[Wikipedia:Sockpuppet_investigations]].
