It does not appear to be a clickbank site.
However, it does appear to be primarily a bad copy-and-paste job from a variety of other sites. The English is badly fractured, so I am guessing that it was written by a non-english speaker. I'm also seeing words that appear to be Russian scattered throughout the english text. It is also filled with errors.
For example, on the http://www.2012earth.net/doomsday_2012.html page, we find the following:
December 21, 2012 - the day of the winter solstice. In the Mayan calendar, the day ends with 5126-year cycle. Maya believed that this day will a movement of the Earth, which would entail the destruction of our civilization. On the same day will the parade of planets. Do the predictions of doomsday in 2012 some kind of truth? Cosmic clock. Should we expect in 2012, the end of a modern civilization, living on planet Earth? It must be remembered that significant events in the world do not happen without any given order, haphazardly and spontaneously, in disagreement with the cosmic laws. Everything has its time and place. We have to figure out whether such a moment occurs in 2012 in connection with some kind of cosmic cycles.
There is no evidence that the Maya believed that "this day will a movement of the Earth, which would entail the destruction of our civilization." That is pure projection by authors who have not taken the time to study the Maya.
There will not be a "parade of planets" (which I take to mean an alignment) on that day.
Contrary to the author's assertion that "It must be remembered that significant events in the world do not happen without any given order, haphazardly and spontaneously…." we find that "significant events" are indeed frequently random and unpredictable.
There are some things that can be predicted with great accuracy. Want to see the next eclipse? There are tables compiled by astronomers that can tell you when they will occur, and where you will need to be in order to see them. Other events are only partially predictable, such as earthquakes. I can tell you where they are likely to occur, but I cannot tell you when or where the next great quake will strike.
The site is filled with these kinds of assertions with no basis in fact and no evidence given.
