This answer on the Bypass MAC address internet time filtering question seems to be a joke answer, half-answering the question using specific terminology (re: timing attack, side channel attack). Obviously these are jargon-jokes. You can even see one in the comments.
I upvoted the answer and that comment because they're funny, but this obviously doesn't answer the question. The answer does link to MAC address spoofing which technically does answer the question, but then it basically becomes a link-only answer, which isn't ideal.
What should be done with this answer, if anything? It's in the Hot Network Questions, so it's just going to garner more attention from this point, so I think a quality assessment is a good idea.
