Any responsible ISP will block this kind of L2 "unknown" traffic between 
customers.

We see this happening unwittingly in the wild as of several years ago with 
Windows ICS announcing RA to both WAN and LAN because it (or thinks it) 
has 6to4 connectivity and wants to share it.

Nothing new here, but the wider it's known the better.
