Thomas, recently you've aggressively rejected suggestions that we make an effort to keep things like blocked notices out of google.
Part of your argument seems to be that blocked people deserve whatever humiliation we can dish out. Cases of mistakes have been made, but you haven't seen to care.
I hope you don't plan to reference your work on Wikipedia in any job interviews any time soon: http://www.google.com/search?hl=en&q=Thomas+Dalton+wikipedia&btnG=Go...
Have I finally made a (wp:)POINT that you can understand?
As a Wikipedian in good standing fixing this won't be hard... but the same problem can be nearly impossible for outsiders to resolve.
Wikipedia isn't judge, jury, and executioner any more than we are a personal webhost. We should probably complexity no-index user and user talk... but if we don't we should at least endeavor to keep block/ban notices out of the search engines.
We must block people to keep the site running well... but using our web presence to attack people is generally unethical, and inappropriate even when they deserve it.
