The broadcast is ONLY done when the wallet is in Receive mode. Same as when the QR code is visible. The use of the *Name* section is specifically so that a recipient can broadcast their name/handle. Not so the recipient would broadcast the name of the Sender.

I hate to break it to you, but you broadcast a photo of your face every time you walk outside ;)

Bluetooth MAC addresses are random, they aren't useful identifiers. If someone can see you, a face is a far more uniquely identifying thing than a MAC.

"Payment spam" might be a problem. I can imagine a wallet requiring that such requests are signed and then spammers can be blacklisted in the usual fashion so they can't push things to your phone anymore. Anyway, a hurdle that can be jumped if/when it becomes an issue.
