Maurice - please go back and look through the whole issue, if you are interested in what really went on. Read some of the posts - not just between Felix and Zoe, but also Moriori, Raul, Dunc, Dmcdevit, Flcelloguy, WP:AN... Felix may or may not have had a point, but he went about it in such a way that if Zoe didn't block him, someone else would have. The purpose of the project is to write an encyclopaedia. We are all volunteers here. No one is getting paid. If someone's main purpose is to get recompense for a past wrong, to extract apologies from Moriori and Raul, to tell El_C that his poem on his user page is obscene... and to get upset when Dunc fails to address his complaint about DESpeigel's post to his (Felix's) user page... We have (foolishly?) donated thousands of hours to this project. With any troublesome user, you need to consider two things - does the user's value to the project outweigh the trouble of dealing with them, and does the cost (to the community) of an admin acting in the spirit of the law rather than the letter of the law outweigh the benefit of a "simple" solution. Dictatorship would kill Wikipedia. Having every problem wind its way sloooooooowly through a hidebound bureaucracy would do so too.
Anyway, creating sockpuppets to evade a block is forbidden. That should be apparent to anyone. Otherwise a block is meaningless.
