After many years and tens of thousands of dollars through my Paypal account I received a letter one day saying my account was permanently limited.  The accusation was "sexually related activities".  I do not know how this was concluded.  I provided plenty of documentation to explain legitimate reasons otherwise for the transaction and it was backed up by the person who gave me the money.  They did not care. There is no option to appeal.
They kept over $600 of my money for an extended period.  The worst part is now I cannot accept Paypal for any reason. There are work arounds (kind of) for buying, but they are a pain in the ass. Using outsource labor is difficult.  I had to have a friend pay for an online webinar the other night and then repay her.
I have joined the class action lawsuit, but the compensation is only $3.00.  
Not sure how important it is to you.  A lot of people don't know how serious it can be.  Just wanted to give you heads up.
