Its already happening to a certain degree.

When the MSM unleashes the words Peak Oil, you can bet top dollar that things are going to be crazy. I suspect this site and others to shut down from the demand. Thats probably the intent too-

MSM: "Peak Oil" "the British are coming" "Fire"

all Peak Oil sites are bombarbed with 10 million SUV owning soccer moms, 20 million college students, and 30 million other large vehicled people- all at once.

Peak Oil sites shut down across the net, with help of government planted hackers. The sheeple never learn the truth as the repositories of information and free thought are cut off from them allowing the propaganda to reign supreme. Fox news wins.

something along those lines. Its like a sad, sad, sad story.

I think the internet is just a little more resilient than that :-) Sure, TOD, PeakOil, DieOff, etc will get bombarded at first and hosting may go down, but the cluefull know how to use Google cache and once the initial furor dies down the masses will listen to talking heads on Tee Vee while the existing peak oil oriented sites cope with a 10X increase in subscribers.

There will, of course, be efforts to spin it just like the effort to spin global warming. Unlike global warming denial we'll see blaming - the oil companies, the {Arabs|Iranians|Venezuelans|etc}, the environmentalists, and so on.

There will be an immediate ferocious effort to undo environmental laws and pillage everything in sight - the environmentalists will be blamed for not permitted the development of the ANWR, and so on.

It'll take a bit, perhaps a couple of years due to depression slowing consumption, but it'll sink in that its us and we have to change here.

sorry but it'a mostly a myth that the internet is that reseliant.
the hosting company that hosts this place and the other peak oil sites do not 'just' host these sites. They like many others host hundreds to thousands of other sites as well. such a ddos(disatributed denial of service) attack might make them tell the people who manage this site that they will no longer accept their busnius or demand that they pay a much higher rate. because this is only one site out of many they host and it's preventing them from getting revenue from the other's.

The effect of blacking out the internet sites might not be intended when they start to tell the populace of peak oil happening now or in a couple of years on the msm. but as you said though they will take advantage of it.

Best to brush up on shortwave radio.
