Use a credit/debit/check card for all PayPal transactions. I refuse to link my account to a bank account
Glenn - I'm sure you know this, but a disadvantage of not linking a bank account is that it costs. The recipient is charged a fee of 4.9% + $0.30 USD and there is a limit of 5 transactions per 12 month period on individual accounts (

So, if someone is going to send you money that is backed by credit card vs. bank account, you should consider having the sender absorb the fees. Maybe I am lucky, but I have never had a bad experience with PayPal.
