I myself have not had any problems with PayPal, but I know of many who have. Here are some sites with some "horror" stories about other people's "bad" experiences. PayPal has gotten so big, and does have a lot of bad users trying to take advantage of others through PayPal. here are some sites if others want to have some good reading:

http://www.paypalwarning.com/

Of course feel free to search "PayPal Problems" or something similar to find even more stuff. Some very interesting reading.
