Those "lost" accounts were all bought by people. Some still use it, some play league of legends instead... There isn't an infinite amount of these accounts so I would just report them. Don't hate me if you already do. :)
You have made several comments with these kind of messages and they really annoy me. Cubecraft's staff team does their best. Helpers, moderators and administrators are doing their best to keep the server a nice place. They help people who need help, punish rule-breakers, but they also get messages like yours. As said earlier, they are doing the best they can and the message you make discourages them. We, the players, probably know half of the things they did, are doing or will do. Because we know so little of what they do, we shouldn't say they are doing nothing neither. Yes, it takes some time before a bug gets fixed. Yes, everyone is waiting for FreeBuild to come back, but it's not that GingerGeek is playing ping-pong with Efcluke instead of working hard.
And don't reply with "It was just a joke, chillex!". It isn't funny at all.
