So the actions of individual users of personal search - taken in aggregate - may affect all search users? Is that how we can read this?
...The system may aggregate information regarding documents that have been removed by a group of users and assign scores to a set of documents based on the aggregated information.
 The IR score, link-based score, and remove list score may be combined in some manner to generate a total score that is assigned to a document. The assigned scores may be used to rank the documents (block 1830).
