Paypal seem to be acting in a very high handed manner and this is unfortunately not the first time, they are clearly abusing their role as a funds transfer facility, the money is of course not theirs to retain for any length of time let alone 180 days, it seems to me that paypals business model is one based on having a near monopoly for those using ebay and as we all know they are simply the same company using two different names and neither pay the taxes they should be instead they hide behind their claims that being based in Luxembourg means they dont have to pay taxes to anyone else.
It would be pleasing if hundreds of govts arbitrarily froze papals money for 180 days to gain tax revenues.
