There have been multiple discussions about down votes (examples 1, 2 ) I have argued that supports of a proposal should ignore malicious down votes but recent events indicate that one person with multiple accounts can go unnoticed unless blatantly obvious.
When I counted on August 3, 2014 the Pastafarianism proposal had 273 down votes, this is nearly three quarters of the required 400 votes to move a proposal from Definition to Commitment phase.
Given that we have a proposal that is being silently attacked by one or more down voters, in what seems to be a clear attempt to prevent phase completion, and we have evidence that up to seven accounts can be quietly puppet mastered; Can one person derail a site proposal on Area51?
