Dear GoW, you seem to have missed something obvious in your little comment - neither time that Giano finished with an old account was he blocked. That does not inspire confidence in your detective skills. Giano has, in the past, attempted to remove himself from the project by scrambling his password; and then decided to return. For Giano, it was considered more appropriate to do it under a new username rather than request a new password (Giano is not the most computer savvy of editors - he rather concentrates on the content than the means of placing it upon the page). Furthermore, very likely the vast majority of established editors are fully aware of who Giano is - and his previous accounts. WP:Alternate accounts does allow people to have different accounts, and even allows them to be used at the same time (but not in the same places, usually) - it is the undisclosed use of multiple accounts, designed to circumvent Wikipedia policy, that is not permitted. I suggest that, when you start digging for information, you make yourself familiar with all aspects of a matter, otherwise you may find that the result of your excavating is that you are simply in a deep and dark hole. Cheers,
