Yes. Whilst it is illegal to *be* drunk whilst editing wikipedia, nobody can ever actually be banned for editing it whilst drunk, because it is also illegal to ASK anyone if they are drunk. And if anyone is asked, they don't have to answer. This may seem bizarre, but it is also the same rules that apply in the House of Commons, and also may fondly remind us of the Laws of Thermodynamics, where it is impossible to break even until you reach absolute zero, but of the law says you cannot ever reach absolute zero in a finite number of steps.
