A good question indeed.
As the network and setup is now. We do log everything. And I mean absolutely everything, in and out. But this is to maintain our security, not to give away to third parties. I understand completely that this can be intrusive for someone and we are planning to change this in the very near future.
We have yet to be asked to give out any information to anyone and we will not unless we are ordered to do so by a court that has jurisdiction in the country the given information is located in.
As more and more of you now know, the Alpha project is moving along and we expect it to be complete somewhere between 1 and 3 months from now. When this happens, we will have a completely new set of configurations and policies. The new alpha web page will also include a detailed privacy policy. And I can guarantee the security vs privacy will be much better.
We do not keep backups of the logs, this is not something we consider vital data for the continuation of Evilzone. Only databases + files are backed up now and then. When it comes to backup storage, it is stored on the server itself and my computer which is fully encrypted. So unless someone breaks into the server, the data is secure.
When it comes to the IRC, there is less logging but still logging. Private messages and non-monitored channels are not logged.
