Alex Harvey takes a look at the 2010 banning of several Wikipedia editors and events since that time - William Connolley has apparently been unbanned, while a more sceptical editor, Cla68, has had his ban extended.
In the case of William Connolley, the [Arbitration] Committee is shown to be extremely lenient, compared to treatment of skeptical editors. William's ban was recently repealed despite obvious signs that nothing much had changed. In the case of Cla68, however, who was perceived to be a climate change skeptic, it is shown that he was banned on the basis of entirely fraudulent claims, and has just now had his ban extended by another six months on the basis of a single frank, out of context remark made in an internet forum.
This double standard - even in Wikipedia - has rarely been so stark. In my view, it challenges the image of Wikipedia as a neutral, dispassionate broker of facts. We see that Wikipedia is, in fact, run by activists who drive away the neutral, objective people who would otherwise contribute.
That should set the cat among the pigeons.
