Needs to be trunk... How do I block the MAC on a trunk? Is that possible?

not sure why you'd think that - the asnwers given back then are all valid

many options, though these 2 are trivial:

1) block the MAC address used for such packets - multicast MAC
01-00-0c-cc-cc-cc

2) set the links to switchport mode access (vtp only works over trunks)
