This is my 2 cents in regards to Paypal.
Paypal is not a bank, and thus does not have to play by anyone's rules but their own. They can freeze your account without reason, not give you an answer as to why they've done this, and ultimately can steal your money without your consent. IMO, they are worse than banks and I regret doing business with them. Avoid using Paypal if possible, because they are accountable to nobody but themselves.
