That’s an understatement, PayPal will pretty much always side with the buyer no matter how ridiculous and outlandish their claim. I even had one “dispute” where the scammer changed the dispute reason which caused PayPal to ignore what I’d already submitted and close it in their favour by default as “no response”. PayPal is very much pro-scammer, avoid if possible.

It’s been a few years since I’ve had to deal with clients directly, I don’t think I’ll ever miss it.
