This is my reasoning from another post:
"Hi Biebs. Columbo here. 743... = Biebs. Biebs
743... posts and
all others. It took a while to figure this out, but the truth has revealed itself. How ingenious...a registered user who only down votes and never posts and an anon who posts, but can't vote. Puffs cigar...
"
KS always asked why Biebs never posted, and then anon 743 posts and gets
from Biebs regularly. 743 goes after Surface similarly. I am an excellent study of human nature and a believer in the Occam's razor methodology of reasoning. Not that it matters in the greater scheme of things. Just my two cents.
