PayPal Nothing new...PayPal freezing accounts for no reason Internet

PayPal is at it again.  So I sell a used Xbox 360 on ebay, accepting the $150 payment through PayPal.  I then get an unusual message on my account page stating they have modified the funds availability policy.  Reading through the entire policy is like reading the writing of a 6 year old.  Lines such as
 "Payments will be held in a pending balance for a certain time period. For example, if you receive a $100 payment (after fees), the $100 will be held in a pending balance for that amount of time. After then, the money will be available for withdrawal."
Can we be any more general and vague about when you will actually have access to your funds?  I have sent two emails to PayPal, as they expressed that as soon as I receive positive feedback for the transaction, my funds will be released.  Well, feedback was left two days ago, and the funds are still frozen.  PayPal and ebay with their greedy, monopolizing ways, are pushing more and more of the people that built their success away.
