However, I do NOT feel that it was appropriate for a single administrator to block a user for four months (in fact, I couldn't find any justification for blocking for WP:PA unless it places another user in danger I think we can all agree that is not the case here). That type of block is, in my opinion, pretty clearly meant to only be handed down by the ArbCom. The WP:BP makes provisions for if a user's block is agreed to by consensus, but that is clearly not the case here, since Karmafist re-blocked Kurt even after he was unblocked by an admin uninvolved with the conflict.
[[Wikipedia:Blocking_policy#Disruption]]:
"Sysops may, at their judgement, block IP addresses or usernames that disrupt the normal functioning of Wikipedia. Such disruption may include changing other users' signed comments, making deliberately misleading edits, and excessive personal attacks. Users should be warned before they are blocked. For dynamic IPs, such blocks should last 24 hours. For static IPs and user names, such blocks should initially last 24 hours, but repeat violators may be blocked for a maximum of one month." http://en.wikipedia.org/wiki/Wikipedia:Blocking_policy#Disruption
