We do not lock people without evidence, and everyone should be very, very happy that we don't.
Understandable, and I don't think anyone asked that all accounts in Aurvandil be locked.
I understand every anger. However, we can not rewind history. What exactly do you want us to do? Can you come up with something that would not have some other group of players complain (and rightfully) for not being given whatever it is?
The bare minimum would be breaking the momentum that cheating gave them. As it is, they are on a roll. All of their beighbors are crippled, and they are already issuing new threats, bullying, and preparing to conquer some of their neighbors again. They've demonstrated that they are too far away for the North to be able to do anything about them, and even with a ton of accounts less they are still plenty able to overwhelm all of their beighbors thanks to the crippled state their cheating left everyone in.
I, and others, favor total realm destruction by now, though. Would they complain? Sure. But why would it be fair that they get to keep their realm as a superpower while all of their neighbors were crushed to their cheating? A realm is not a right. If a realm was acquired by cheating, then no one is entitled to it. Just like when you acquire a stolen good, even through legitimate means, you are not entitled to it. Why would justice be any different in a game than in RL? The honest players can then try to rebuild their realm legitimately. The injustice suffered by these players would be far lesser than the injustice that was suffered and is still being suffered by the players of the 'moot playing fairly.
Also, what people seem to be forgetting is that we have invested a lot of time and effort into investigating Aurvendil several times. It makes me sad to read that people think we don't care, because we do. We care about finding cheaters and we care about protecting good players. Most importantly, we want to be sure that we don't lock honest players as cheaters on some kind of overzealous inquisition.
Yes, I would rather let someone I suspect of cheating stay than lock someone who might be innocent. I am very sure that if we are talking not hypothetically but about an actual innocent player, say, you, then you would agree with this in dubio pro reo approach, yes?
Hence the difference between sanctioning players and sanctioning a realm. Even if you lock for 3 days all of the people that support Mendicant's return... What will that give? Their supporters will keep their titles and they will resume profiting from everything the cheating granted them once the 3 days expires. Having the realm destroyed, however, is not a punishment to any of the legitimate players. Realms die all of the time. And if they are that many and they truly are that good, then nothing will prevent them from sticking together and rebuilding a realm. But they should rebuild it fairly. Destroying a realm that massively benefited from cheating and that is glorifying the cheaters after the fact, fully knowing what was done, is not anywhere near the same thing as locking random people with little proof.
I wish to add, however, that I am greatly concerned with Dustole's report of new accounts being created with similar traits as the locked accounts... The players of Aurvandil looked the other way during years. Who will report these cheater accounts now that Allison bailed the realm? Who will prevent Mendicant from recreating all of his alts?
