That's right - you don't have to have done anything ban-worthy. They just arbitrarily decide to ban you, inform the secret list, and that's that. This is something those who were never in the head clique always knew about, but it's the first time someone actually revealed how frequently it goes on.
Not just possible, but extremely likely - in my experience, far greater than 90% of "suspected sockpuppets" are really editors who're just being harassed by abusive administrators trying to get a bannable rise and control an article.
The list is hosted by Wikia, the Jimmy Wales-founded open source web portal that was setup as an entirely separate entity from the not-for-profit Wikimedia Foundation that oversees Wikipedia.
The sign-up page explains that the list is designed to quash "cyberstalking" and "harassment." But it would seem that things have gotten a bit out-of-hand. Clearly, the list is also used to land "the banhammer" on innocent bystanders.
"The problem is that their false positive rate is about 90 per cent - or higher," says Kelly Martin. "It's possible that every last person Durova has identified is innocent."
Of course, looking back, this would appear to be the same hidden list responsible for what I was sent earlier this year.
