  == Possible sock issue related to subject - PR agency at work? ==  I am also noticing strange acticities related to the subject like [] and [] just today. Even though the edits were on related articles and the timing is very close, they style of edit coupled with the similarity of the content added makes me think a sock is being attempted. A glance at this article's history page also show suspicious activities by SPAs whose only other activities are to add information about the subject in other articles.
