It’s not PayPal’s job to investigate whether a particular game of poker is legal or illegal. That’s why they just ban all transactions peripheral to gambling. If you’re going to use PayPal for poker night, just don’t mention that word anywhere in your use of the application.

A lot of PayPal’s complex enforcement algorithms seem to be merely word matches. Someone I know as a joke said “Kim Jong Un” in the message when he paid for his half of dinner and got his account insta-locked for weeks just like that.
