I can understand the reason you gave, it is to hide the issues from adversaries. But you being away silently and then show up with no proper explanation not even a clue makes users a bit worried, including me.

I value the service you have been providing, the whole bitcointalk community does. But if you were compromised in any way then your user's privacy is at stake too. As the coins you issue are anonymous, but there is a connection between those coins and the coins people send. That is Chipmixer. If it was not DDoS or any other technical issue then what was it? was it some kind of breach. Is our privacy compromised?
