I have no evidence for this, it's just my assumption from watching Josh's videos around that time. But I'm pretty sure it was Snails who sent one of the sex dolls. And I'm pretty sure he and his crew did something to it before sending it. Josh mentions that there is something wrong with the fingers, like it came with a few cut off. Seriously some serial killer kind of shit, but I think they did it to make Josh seem worse?
Also, if it was sent by Snails with it's fingers visibly cut off, what else did they do to it? Could you imagine sticking your dick inside anything that was tampered with by a troll? Josh does.
I don't know anything, and this is all just speculation. In the videos around the sex dolls are super fucking weird and it's a bit hard to parse it all out.
