A tipster tells us PBwIki — an enterprise collaboration site used by companies such as Cisco, AT&T and Citi — mines the content its customers upload for email addresses to spam.

I got an email from pbwiki even though I wasn't signed up for any kind of a mailing list or anything, so I emailed them about it. They only had my email address because it was the content in a wiki hosted with pb wiki and they dodged the question and just talked more about the content of the email. They're definitely helping themselves to all the data in their user's business wikis,

PBwiki founder David Weekly denies the charge entirely and tells us: "PBwiki does not have any scripts to go through private wikis and scrape for email addresses." Update: In the comments, Weekly calls this story "bullshit of the finest and legally actionable kind."
