Just another example of the type of ignorance we have been dealing with ever since the day RSA was invented. Unfortunately people still don't get the Rivest-Silverman paper:

To be brief, there exists infinitely many algorithms that rule out classes of so-called "weak primes", or "weak moduli." Such attacks are meaningless because you will not know which algorithm will crack a randomly chosen modulus until you try it. By trying algorithm after algorithm similar nature to this, your expected run time is exponential before you find one that works. Which essentially means that the concepts of "weak moduli" and "weak primes" are misnomers.
For an algorithm like this to be meaningful, the density of primes that it rules out needs to be significant. In this case, it is insignificant (it is exponentially small).
