Bans, deletions and their consequences are not publicly discussed. Game Support does not disclose information about bans to individuals other than those involved. (This can be read in the game rule §7.2).
Rule 7.2, as I read it, prohibits players from discussing their bans, deletions, and consequences in any manner other than via the Customer Services portal. It also states that the Travian Legends team does not disclose information about bans to any individuals not involved. Fair enough. However, I don't believe anyone here has asked about anyone that has actually been banned or why they have been banned. Candidly, I think most players can figure that part out for themselves.
So perhaps the more specific questions, and questions the appear to be in compliance with the rules, are (a) what accounts in the Istanbul meta have been reported to and checked by Travian Games but have not been banned and (b) what was the reasoning for them not being banned.
P.S. I will note that rule 8.1 allows Travian to change their rules at any time. So Travian using their own self-created, self-imposed rules to not be transparent in this matter would certainly be disappointing.
