To the best of my knowledge, it is still an open question as to whether all the zeros are simple. If you could find that article....

For what it's worth, any number of "proofs" of the Riemann Hypothesis have appeared on the ArXiv. Here are a few (I've not included three more that were withdrawn by the authors).
