Rest assured that the moderators are well aware of this user and his sockpuppets. 

I have now placed this question under <a href="http://meta.stackexchange.com/questions/52764/what-is-a-protected-question">protection</a> so that these entities cannot post further nonsense. The usual basins of attraction for this particular user involve RH, the Goldbach conjecture, the abc conjecture, and sometimes primality testing, and I have occasionally placed other questions which have these terms under protection as well.
