Yeah, running into douchebags in MineZ is not the same as when you run into some on DayZ. The combat and mechanics are vastly different and it can ruin everything for everyone. There is no escape, if you're going to get screwed there is absolutely no way out. The private servers risk this less, it contains people who want to survive and work together - then there are also people who want to survive but have become paranoid, and will do anything to survive. It's not the same type of thing you run into on a public server.
