I'm still up for playing it. I still have my full equip profile, being alive for 10 months now or so (with 2-3 months of actually playing), but I'm somewhat interested to start from scratch again.
Biggest problem is that retards host the servers and add a shitload of vehicles. Every server says like "DayZ 300+++++ vehicles" To me, this fucks up quite a bunch of things. I remember stealing some guys pick-up with a mate. He missed the shot on one of them and we crawled around them to the truck, got in and drove away under heavy fire. THis was awesome, but only because vehicles were so rare.
All the magic about this game is gone with so many vehicles in my opinion. Nothing you can really look forward to anymore. I really had a tough time to find a server with normal amount of vehicles. Anyway, if I'm not mistaken the [F|H] server is going to be relaunched very soon and there actually were people playing on it.
Don't know about hacking, but I think many servers are password protected now. Maybe the hacker community lost interest in the game though.
