its not safe using paypal to buy bitcoins. It will be very hard to find someone accepting paypal. But goodluck finding some1.
Its not too hard actually. Its already been said in this thread. People will accept it with a mark up, and also, the buyer is required to send payment as a gift so there cannot be a charge back. Look on localbitcoins and refine by paypal as payment method. You will see a ton of people willing to do this.
