It was much easier then because most exchanges didn't deal with AML procedures, they just took your word as to who you are. There were also a lot less scammers back then so most exchanges would accept reversible payment methods.
I still don't understand why exchanges have to make it very difficult to buy Bitcoin. I would love to just create an account and buy directly with my visa card at market rates. Can't that be done and still be in accordance with AML procedures? All this personal id verification nonsense and directly connecting your bank account is what is holding back bitcoin and putting off a lot of people.
