I present the evidence as I see it.

TL;DR

txbtc was bought by Operatr. txbtc was later banned. leancuisine, Operatr, gysca, txbtc, P4ndoraBox7 and CanadaBits, Miyslovenic, Funny, tennozer, PrivacyLock and vCardVideo are alts. Alts are still active after ban occurred therefore they are guilty of ban evasion.

Occasionally I go over old cases in an attempt to uncover new connections, or, to verify that the previous information is sound and that it continues to hold up to scrutiny.

I had a look at the list of users who DT Trust leancuisine:

Miyslovenic, Funny and tennozer all carry one avitar:

while

leancuisine, Operatr, gysca, txbtc, P4ndoraBox7 and CanadaBits all carry another avatar:

We can connect the first cluster of three with the second cluster of six UID's through five of the nine UID's having woken up on the same date:

6/20/2019 10:09:30 PM    woke up      Operatr      (Group 2)
6/20/2019 10:38:04 PM    woke up      Miyslovenic   (Group 1)
6/20/2019 10:38:58 PM    woke up      Funny      (Group 1)
6/20/2019 11:03:17 PM    woke up      tennozer   (Group 1)
6/20/2019 11:01:51 PM    woke up      leancuisine   (Group 2)

We have a third cluster of four UID's - Maidak, dominicwin, PrivacyLock and vCardVideo who carry no avatar.

Of these four PrivacyLock and vCardVideo were last active 1461 days ago the same as gysca from group two.

Registration Date:1/10/2014 7:25:25 AM    (Active 1461 days ago)    gysca      (Group 2)
Registration Date:4/10/2015 10:12:30 PM   (Active 1461 days ago)    PrivacyLock      (Group 1)
Registration Date:4/24/2015 11:11:05 PM   (Active 1461 days ago)    vCardVideo      (Group 1)

Maidak and dominicwin from a cursory glance do not appear to be connected to the other eleven UID's, however, it should be noted that Madiak has four negative default trust feedbacks from five years ago for having run off with other's money and in March 2021 they tried to sell their twitter account:

Have had it a long time now but I no longer have a use for it and would like to see if anyone would like to purchase it. If anyone wants a crypto related twitter account with about 4000 followers send me a PM. Price is reasonable.

[Edit April 26, 2021, 10:38:29 PM]
It is potential and active 100% audit and usa based followers/investors.
If you want to check the account inbox me.

Maidak is DT trusted by leen93 who like txbtc was banned on the same day:

Although I can't pin a connection of Maidak to the eleven UID's in this cluster, it is clear leen93 is a twelth alt through leen93 and txbc banned within hours of each other and their both DT trusting/trust of Maidak.

Miscellaneous:

Whilst looking at the user account_seller777 / farlack that has been connected recently by @Ratimov, I was following some DT trust links and noticed this (not connected to account_seller777 / farlack at least AFAICT)
