A: is there any progress toward solving Gilbreath's conjecture

Though Wikipedia updated their statement as to the lack of a proof from "as of 2009" to "as of 2013", this was exactly the time period in which appeared not one but TWO "proofs by induction" of the Gilbreath Conjecture! Yes! They passed through the "search filters" of at least Google and those av...

The above post seems to refer to Hashem Sazegar: An Elementary Proof of Gilbreath’s Conjecture and Zhang Tianshu: Legendre-Zhang’s Conjecture & Gilbreath’s Conjecture and Proofs Thereof.

Should it be simply deleted? It seems a bit as a crank post/advertising.

specific-question Once again about the same question - is there any progress toward solving Gilbreath's conjecture. I have added the tags open-problems and conjectures. However, these two tags seem to be a bit similar - I am not sure which of them I should have picked or whether they both belong there.

Probably I should have also add capitalization and question mark to the title - but probably it is not worth adding yet another suggested edit just for that.

Q: is there any progress toward solving Gilbreath's conjecture

Gilbreath's conjecture is a hypothesis, or a conjecture, in number theory regarding the sequences generated by applying the forward difference operator to consecutive prime numbers and leaving the results unsigned,Gilbreath observed a pattern while playing with the ordered sequence of prime numbe...
