In addition to the "Revenge of the C-Students" dynamic I've discussed before, a big problem with WP is that administrators deliberate in secret, so their "reasoning" behind a decision cannot be assessed. My block involved one admin bungle after another. The biggest bungle was the total absence of compelling evidence for the block. Others included the invocation of inconsistent standards of evidence. First the SPI was closed because (the admin said) I was not guilty beyond reasonable doubt; later I was blocked, even though no additional evidence was introduced, based on a lower standard of "reasonable suspicion." Clearly, the admin didn't read the procedures for SPIs before rendering judgment. 
 Also, Srich, you've inadvertently lent support to my narrative on WP. You switched your 'vote' on whether I am a sock solely based on the opinions of others, or on a fallacious appeal to authority. By WP standard, you'd make a great admin.
