So my idea how to solve people creating fake accounts to boost their main.
Instead of creating account for each travian server, have The travian account from which one plays its servers.
Completing servers helps level up that account based how well you did and makes servers not based on regions
but let them have minimum account level requirement.
This would make getting fakes account to high level servers a lot of work and if they get once would need to start from scratch .
also added befefit of having players of similar skill level.
