Different remote viewers and people in that area say different things.
On his forum, we say “UPG is UPG”… Unverified personal gnosis doesn’t mean anything, other than that’s one person’s interpretation of their subconscious impressions
The Remote viewing team at Farsight have a lot of youtube and paywall videos about the prison planet concept. They believe there are reincarnation traps that function to send back those trying to move on past the planet back to Earth.
The Gnostic Christians considered it a prison planet, or more accurately, a farm, where the Demiurge called Yaldabaoth trapped a higher being (the Adamus maybe bit I forget) and split it into shards, using these animal incarnations as prisons, and that is why we get a mind wipe and limited senses when we incarnate. But to be fair they are very black pilled. 
The purpose of this was to feed off our energy. (The films the Matrix are very Gnostic, so you’ll probably recognize the theme.)
Nobody knows, it’s a theory that brings more questions than answers. There’s a lot of speculation but I think that’s mostly a waste of time, listening to speculative hot air doesn’t get you anywhere.
To approach this magickally, you’d want to contact an entity and ask them. You’ll still get UPG but at least it’s your UPG.
That would be us. You, me, the mages here and everybody who seeks to know.
They don’t. They might need the energy… Apparently and per the Gnostic view. IF you believe this s real. I’m not entirely sure I do.
Following the model here, this is usually touted to be because there’s agreements and hands-off ceasefires to do with the Earth.
There’s no “who” here to contact, it’s this one guy possibly building castles in the sky in him imagination. You’re asking detailed questions about someone else’s fiction.
No it seems integral to being human - the human animal itself doesn’t have the ability to communicate effectively. But it can learn. And every life you learn in means it gets easier in other lives.
This is my version of that: I now have a couple of entities who have sort of “offered me a job” as it were, after this. Doing what they’re doing essentially.
If you also try the search for different keyword combinations you’ll see more ideas. Search for “reincarnation traps”, “prison planet” etc.
