Hello. I have evidence of rampant account sharing with players involved themselves admitting that they play each other's accounts.
[s1647]Vaggelis (former name [s1647]ChevChelios which is why everyone calls him Chev) was an officer of [s1647]berlin guild with [s1647]lare being that guild's leader.
2 days ago on May 13 they had a quarrel over something after which Vaggelis has left the guild.
Later that day the guild was disbanded and lare's BR went down several hundred million.
Then the following exchange happened in world chat and pm:

As you can see the guild was disbanded twice and both of them admit to having access to each other's accounts.
Vaggelis is Greek while lare is German which is why they are speaking English and not German so they aren't close relatives living together either.
I also have evidence of lare using accounts of other players and while most of it is unfortunately circumstantial, it should be easy to check on your part.

I've reported these players before and no action was taken.
If this kind of proof is still not enough for you then me and several people from our guild will quit this game,
but not before refunding as much money as possible and/or selling our accounts, since you're not enforcing your own rules anyway.
