Paypal have had their share of bad customer experiences. However it is clear in the Paypal policies that trusts are not allowed to own accounts. If someone was ignorant to not notice that, I believe it is unfair to point fingers at Paypal.
I have to agree. I can forgive a random individual for not reading a ToS, but as a business? That's unforgivable. PayPal might be skeevy, but you can't fault them when they follow their own written and publicly available rules.
