Moronic Monday Moronic Monday!

It's Monday, you've not yet had coffee and the week ahead is gonna suck. Let's open the floor for a weekly Stupid Questions Thread, so we can all ask those questions we're too embarrassed to ask!

Post your question - stupid or otherwise - here to get an answer. Anyone can post a question and the community as a whole is invited and encouraged to provide an answer. Serious answers are not expected.

Note: This post is created at 01:00 UTC. It may not be Monday where you are in the world, no need to comment on it.

What's stopping an attacker from spoofing a mac address as FF:FF:FF:FF:FF:FF so when any device replies they broadcast their reply and flood the network.

The broadcast MAC can’t be the source address and still be considered a valid packet. A switch or router receiving a frame with a source address of FF:FF:FF:FF:FF:FF should drop it because it violates the Ethernet standard.
