This is a game though, there is absolutely nothing stopping one or several of the bandits from having multiple accounts.
The other accounts can be used for the tasks that will reveal identity. Stolen accounts too.
No matter how well a game is made there will be ways around every obstacle preventing people from getting ahead through other peoples' torment.
This game is so attractive to the wrong types of people who can seize and keep complete control of anything they want.
In other games I've been in clans who've phished hundreds of accounts from rival clans. They weren't being robbed of items, they were permanent sources of information on the location of other clans, their plans and an opportunity to cause trouble for them.
I've even seen a rival clan's website announce that they're disbanding the clan because the admins have been hacked.
I can guarantee you groups like that will flock to this game.
