Let's make a list of users that JoshZ has banned for sockpuppeting.
JoshuaZ was a Checkuser (is?), so politely declines to ban himself. But lets see how he applies his rules to others.
QUOTE
JoshuaZ, thank you SO much for accusing me of being a sockpuppet of someone who joined almost a month AFTER I did. Thank you for kicking me off wikipedia. Thank you for not checking to see if my internet provider used dynamic IP's, so that muliptle computers could have similar or matching IP addresses. Thank you for never contacting me about this before you made this decision. Thank you for showing me the true nature of Wikipedia, a community of people who will pass judgement on the innocent to punish the guilty. All the times I made articles, all of the vandalism I helped revert, all of the genuinely fun conversations I had with other users, mean nothing becuase my IP address matched some unfriendly user. Thank you JoshuaZ for making me wish I had never even heard of Wikipedia! Coronis
