The Australian guy is Peekay, here is his breakdown of the Bombing hoax: https://www.bitchute.com/video/9IfLwGW2byHx/
It is off YouTube indeed.
Try the "JFK to 9/11: Everything Is a Rich Man's Trick" documentary. A good overview on a lot of subjects and is a good starting point for a lot of rabbit holes. Dig deeper from there. Should be able to find it on YT or Bitchute.
This one's weird.
If it's a "real" (i.e. not a false flag) event then civilians weren't the target, the messages broadcast by the van warned people to evacuate the area. If the target was AT&T then perhaps it was successful, as it caused massive outages, but that's only half of the story then as we don't know what the outages were useful for.
Follow-up: https://www.bitchute.com/video/9IfLwGW2byHx/ is a good presentation about the Boston Bombing that's been scrubbed from everywhere else.
In 2013 I would have given you a dozen links to great videos by great researchers that busted it wide open, but since the widespread censorship and silencing operation (see my reply to OP's SS) the information is very scattered. Some of it is on BitChute but we probably lost forever the majority of the work.
Sandy Hook and the Boston Bombing were torn apart and exposed as blatant false flags right after they happened. Can't even find that stuff on YouTube anymore, even though it was all over YouTube back in the day. Some of it is on BitChute, but very scattered. But the silencing operation was successful in shutting down and demoralizing so many great investigators with lawsuits and deplatforming that they don't even bother anymore.
It's scary how much this feels like "1984". History rewritten, perpetrators "straightened out".
In the documentary Massimo studies and explain every bit of evidence indicating that we did not go to the Moon and that the photographic evidence was faked. Being a professional photographer himself and by soliciting opinions of other professional photographers, he takes it a step above most documentaries that delve into the subject. Sure, he may be wrong in some cases, but most of his points are bang on.
As for the reddit post, it may be a bored hardcore skeptic that can't handle the attempt at blowing his mind and freaks out in response, by "proving" every point of the documentary false. The account history seems to indicate that u/321 is a devout debunker.
A11 work and no play makes Jack a dull boy
This is the type of shit that stopped me from browsing reddit. From "innocent" subs like /r/pics to state/city subreddits and almost everything else, the same narratives at the top. "look at these bad people not wearing masks", "vaccines are great", "orange man bad".
Not a medical doctor, did a public pandemic excercise months before COVID, talked about depopulation for years. And people bow down and listen to his numerous TV appearances as if he's the foremost expert on this shit (and he is, just not for the reasons he wants you to believe).
People blindly believe anything MSM tells them, this is the biggest problem unfortunately.
