Killed by a DayZ:SA Hacker! What should i do? Are Hackers killing this game?

[Internetarroganz]

Hey, today i played in a group with 4 People DayZ:SA. We were in the village Kamyshowo. We know:,, In some days there is the new update with the new update and the character wipe" so we camped 2 in the Kamishowo Police, 2 on hills. We wanted to use our loot "Ghillis, AKs, Mp5s and many more" So we wanted to kill some people, cause this was our first time we was so full equipt and we dont wanted to just lose this loot before we did something. So we camped and killed people. We killed like 6 People on a 50 Person Server. Then nobody was in the village except an Clan leaving the village. So we was like: Okay lets log out and then someone came in front of us in the police, we killed him. After this my friend screamed:,, GUYS IM DEAD, A Hacker" We asked them what happened and he said:,, Something teleported in front of him and he was instant dead" So we was camping in the police. Every door in the police was closen, so we could hear if someone comes. Then like 30 seconds after the dead of our friend we both were unconscious and then dead. Our last friend died to this hacker. We didnt heared like the 6 times before an door, which opened or steps. My other friend died last and he could see, when someones enter the police. After that we was mad and someone added my friend in steam. The name of the Person was "Dex" and he wrote:,, Thats what hackers like you get.
Silenced Flaminqo was hacking, i saw it. You dont hack to kill people!" And we known that this was the hacker. So we wrote him and told: We are not hacking and is it okay to kill someone with hacks?" and the hacker just wrote: "<3". We are not mad, because he killed us, because we wanted to die, cause there will be a wipe anyway. But why is he killing someone with hacks? I mean im "Silenced Flaminqo" And i dont hack in any games.

So my questions are: Are there many Hackers like this in DayZ? I just meet 2.
Is it worth to play DayZ more if we get killed all times by hackers?
Can i report him somehow or somewhere, so he gets a ban?

In my entire DayZ playthrough, I have never ran into one hacker.
Just switch to a different server.

all time try to play in servers whit ts3 because there are the admin's and they can report them to battleye , in public server's , there are most of hackers because in private they cant do duply (they can duply their inventory , gun's ammo) so they dont go private , thoses are my tips/advices (sorry4mybadenglish) have fun
