How did you get your money back from PayPal? The website tells me "We're sorry, but this transaction cannot be disputed because it is not a purchase of goods or services. Please contact the recipient directly."
Did you call PayPal? (I have to wait until they're open)
Only sent them $100 bucks, but clearly I should've done more research. Their website didn't really set off any alarm bells for me. But the last time I bought bitcoin (years ago) I had to take cash to the local drug store and get a moneygram type deal. I had hoped it had gotten easier, but I guess not.
