In the notice, I stated:
"So much of masquerade operations relies on the honor system."
I've lost count of the times, after any major cosplay competition, that serious accusations of favoritism on the part of judges and directors were made. I'm not going to go into all the factionalism and infighting that has followed them.
There is no hidden cabal that controls cosplay or costume competitions. There is no secret order of masquerade directors that maintains blacklists (and if there is, I don't want to be part of it). What we do is all based on the honor system.
Our only recourse after a violation is to publish the evidence and our decision in the same communities and forums where the masquerade awards were published. It's up to the readers, whether they be conrunners or other cosplayers, to review the evidence and decide how bad they believe the infraction is.
