User::spreadBlock() contain the line $userblock->doAutoblock( wfGetIp() );, added on r17486 There's no function wfGetIp(), it is called wfGetIP(). Although given that there were no reports in almost 3 years, it might be dead code which should be removed (even if only blocked people reach there, there woud have been traces in the logs).
PHP function names are case-insensitive.
