Loops, do you mean cold reading or how experts get it from the sites they contract with? Cold reading is well documented and can be searched up, plus once you're away from reads suddenly you see it easily if you read over read transcripts, but I don't think you mean that.
The stories I heard simply were that some experts did have contacts at their sites which did feed them info. We did have some examples at the time, but again it's a few years and while I do have old emails, I don't have access to the old group anymore. But we did have a few rogue experts giving us this info for whatever reason. Some were questionable but thought they were different to other readers, others were honest ones (right or wrong as readers). Feedback is often removed as you guys have seen. And we heard stories directly and indirectly about there being people at the sites willing to give experts transcripts from clients from other experts. Not that they can't get those on their own if they strike up their own sharing relationships, though!
And regardless of ownership, these sites are there to make money. The fact that AT&T owns Keen (had no idea) is distressing though, as that means they own a site that scams people for cash. Since there's a lot of shame and secrecy around getting reads, and since these sites hide behind "for entertainment" terms and all of it is just stuff someone's telling you that you're meant to believe, I'd imagine they feel they can't get sued or taken to task.
