The Dutroux section of that website is very good. But you have to be careful there. It's a limited-hangout website.

Some here may know the commentor "Brabantian" from various website comment sections, Unz, Winterwatch, Aangirfan and he also writes articles on henrymakow.com.

Always insightful, he has pointed out some very interesting things about isgp-studies.com that I have noticed too.

I was going to write a long comment, but's just easier to copy/paste what brabantian has written (copied from the comment section of a winterwatch article on dutroux)

Looked a bit more into that ISGP website linked above, with Dutroux files so usefully gathered … Sadly, ISGP site owner Joel van der Reijden is another ‘limited hang-out’ serving intel agencies & Israel.

This can be seen from Joel van der Reijden’s lists of what he believes, & whom he denounces as spreading ‘hoaxes’ and ‘false conspiracies’.

Joel van der Reijden & his ISGP claim “Osama bin Laden ran 9/11” … with help from USA, Saudi Arabia, Pakistan & Russia (!) … but ignores Israel HA.

Joel of ISGP claims that an aeroplane “hit the US Pentagon on 9-11” … despite how even US Army Major General Albert Stubblebine III, declared with certainty there was no aeroplane, as Russ Winter has just reminded us:

http://www.winterwatch.net/2016/12/30/major-general-stubblebine-interview-911-was-a-false-flag/

Joel of ISGP believes ‘high level satanism’ is ‘bogus’ … and that much of ‘ritual abuse’ of children is ‘potentially bogus’ … and that there are not so many children ‘disappearing’ as claimed

Joel of ISGP says there is nothing amiss with chemtrails

Joel of ISGP says the USA claimed ‘moon trips’ & ‘moon landings’ of 1968-72, were totally genuine HA

Joel of ISGP says it is absurd to talk of the NWO – New World Order, and that the Rothschilds are not running the world, whilst Joel fervently affirms the Holocaust

Joel of ISGP claims Edward Snowden is genuine, tho he admits it ‘odd’ that Snowden, Glenn Greenwald & Julian Assange receive millions from CIA billionaire Pierre Omidyar … Report at intel agencies ‘Snowden, Greenwald are CIA frauds’:

Joel of ISGP says that there are no ancient civilisations or great structures before 3500 BCE & Hebrew Bible times, the Sphinx is not so old etc … despite how there is much evidence of more ancient dates of civilisation in India, Anatolia Turkey etc

It seems what the intel agencies do, is establish a go-to site with credibility in certain areas, like ISGP with Dutroux … And then use the prestige with the audience they have won, to, e.g., cover up Israel’s role on 11 Sep 2001, as Joel van der Reijden, Glenn Greenwald, Edward Snowden, & Julian Assange all share in doing

"the finders" is a rather deep rabbit hole as well.

FBI, CIA, foreign intel agencies, hippy cult of child abductors all tied to satanic ritual goat slayings, hidden rooms under pre-schools filled with hundreds of dead animals bones and maps of secret tunnel networks under DC.

all of this was under the guise of a "school for gifted kids in mexico, and/or japan" while the kids were malnourished, showing signs of sexual assault, dressed in rags, haven't bathed in days, covered in insect bites...

everytime local PD got onto the case, the feds got involved, returned the kids to the cultists and told the local yokels to drop it while they disappear the evidence.

...But it's probably nothing...

and this is just the tip of the iceberg.

The site has alot of good stuff. I just got turned on to it and figured I'd share.

OP note: as per u/clemaneuvers, ISGP could be honeypot/limited hangout.

The difference is that Dutroux is real and Pizzagate isn’t.
