This is a working theory.

I am investigating a connection between theyoungmillionaire and finaleshot2016 who both changed their passwords within 24 hours as I stated in this post and this follow-up post.  jademaxsuy along with crwth have extensively swapped merits with theyoungmillionaire and finaleshot2016 while in @LoyceV's Default Trust List Week 05 jademaxsuy removed their trust of theyoungmillionaire only to add finaleshot2016 and crwth in Week 06

In addition, I have a working theory that theyoungmillionaire has at least four or five alts being jademaxsuy, finaleshot2016, Squishy01, GDragon, Strufmbae, Silent26, crwth and Maus0728 based on their default trust lists activating the same week for most, or a couple of weeks later (with the same list) in the case of the latter couple of UID's.  As at week 76 all or most still trust theyoungmillionaire and each-other.

Since my first post, Maus0728 has removed their trust of theyoungmillionaire but continues to trust all others (the group in what seems to be a DT abuse cluster).

An example of the alt DT abuse is as follows:  (and it's an incomplete list of the week 76 examples)

In purple the first group that appear to be connected, with those in orange seemingly connected as well via adding the same core ten UID's as those in purple.

Week 76:

Compare the above to this week:

This investigation is still ongoing.
