A question about Sevastopol's banning

Of course, I am compelled to tell you this by the Agency.*

*a shadowy organization that Sevastopol once postulated as directing the comments of his adversaries in Dope threads about Israel.

I found that comment, out of curiosity.

Now, overall the question is constant: How does it come about that in this day and age people with access to the internet can voice such easily demonstrable errors of fact; as Weirddave and Valteron have done? Where do these opinions come from? An agency of some sort seems the likely answer.
