Have you guys heard of the DBoS (Distributed Boycott of Service) against PayPal today?
http://twitter.com/#!/search?q=%23oppaypal
Thousands (me included) closed their PayPal accounts. Rumours say 20,000+ accounts have been closed. If you still have a PayPal acc I urge you to give them the finger and close your account. #oppaypal was the #2 trending topic worldwide until a few minutes ago (typical twitter censorship)
It doesn't necessarily prove causation but Ebay stock was down 3% within a half hour of the markets opening.
EDIT: Twitter finally grew a pair and uncensored #oppaypal after a huge backlash
How do I post an image? I'd like to post a screenshot
