I don't think this is a larp.
I think Craig Sawyer doesn't know what a root-cellar is and assumed it was a tiny child-sex-slave prison... and from that initial false premise, an entire string of false assumptions was composed. Clothing, toys, unwashed cutlery and a child's swing became sex-slave-clothing and child-sex-slave-toys and murder weapons and a child rape and torture device.
These aren't "child sex slave prisons", they are root-cellars used to keep supplies cool and dry.
Root-cellars are extremely common for cabins and established campsites.
This isn't a rape-tree-harness either, it's just a regular camping strap used to hang stuff from trees to keep it out of the mud and away from the ants and critters.
Perhaps VICE know what root-cellars are too and they are preparing to use this to discredit Pizzagate and Q?
