For transfers between "friends and family," there aren't any fees, which probably drives a non-negligible number of account creations. That said, if PayPal thinks your transaction is not between "friends and family" (despite being marked so), they won't hesitate to freeze those funds while they investigate. A couple years ago, I used to send my portion of rent to my roommate via PayPal, and they froze the funds once on him. Surprisingly, he was able to get them unfrozen pretty quickly. That free transfer system in combination with being a "safer" payment option offered by some merchants makes PayPal pretty attractive to the average customer. And -- most of the horror stories come from merchants, not customers. Even though I try to avoid PayPal on principle, it's hard for me to convince my friends to care.
