According to a report in Canadian newspaper, The Globe and Mail:
"Wayne Crookes, a former campaign manager of the Green Party of Canada, said he “suffered an immense amount of frustration and emotional distress” over postings on Google's Blogspot.com, a free blog-hosting website, within an entry under his name in Wikipedia, and on openpolitics.ca, an interactive political forum set up by Michael Pilling, an Ontario and federal Green Party activist."
The cases against Google and Wikipedia were filed earlier this week in the British Columbia Supreme Court and the suit against openpolitics.ca was filed in May, 2006. All three lawsuits relate to comments posted by members of the public on discussion areas of the sites.
