I only followed these people (or one person) a couple of levels. It was obvious enough and I didn't want to waste more time.

For example Acathers had two feedbacks (the two I tracked) one was from echostar-sales, who had only 2, from 1) acathers and 2) subduing-mara, who had eight, of those eight one was echostar-sales and the rest from four more no longer a user, (some from legit users) Amanda-Coberly was one of those, who had the same situation, plus negatives.

The second Positive was also from a group of no longer users, and that persons only positive was also from acathers. The rest of the ring was the same names.
