  This is a reformulation and refutation of a proposed proof of the Riemann
hypothesis published in 2013 (arXiv:1305.0323) and in 2014 (arXiv:1402.2822).
Proceeding by contradiction, the author wants to prove that if zeta(s)=0 where
1/2<Re s<1, then zeta(2s)=0, which is known to be impossible. We show that both
versions of the proof are incomplete.
