User blog comment:Wildoneshelper/Having a "sockpuppet" account makes you blocked? Ridiculous!/@comment-24914201-20140808104013

Olaf had two accounts but in the wiki's rules, it's written :

Sockpuppeting becomes unacceptable when sockpuppets are used to: This also includes simply logging out and editing from an anonymous IP to avoid recognition.
 * Conduct prohibited activities without them being traced back to your primary account
 * Get around a block on another account
 * Manipulate the outcome of a vote

Olaf had not used his account for one of these reasons.
