Here's my story, and why I think devs should do something about it:
I started playing 2 days ago, with a couple of friends. We settled, and soon found hostile players. Soon we met friendly players; their camp had just been destroyed by the same hostiles that bothered us. We decided to unite and move away. We settled in a couple of hours, built a house, started our little camp, while one of us was gathering points to get a claim. A couple of hours later our house was destroyed, and our stuff trashed.
The next day, me and my friends decided to move again, far away (a couple of hours IRL) this time, and leave behind the "friendly players" who didn't want to move.
We settled, built a house, a bunch of crates and started our camp. The area seemed clear, barely anything built by players in a good radius around us. that was yesteday.
Today we started our little claim, just big enough to claim the house and a few more blocks, since my friend didn't have enough LP to claim more. About 1 hour later, a fresh spawn with nothing but a bucket came to us. He trashed the stuff we couldn't claim yet (e.g. removed and threw on the ground stuff from the drying frames), and then began destroying everything we had out of the claim. Frames, plower, table, chests, piles of items.. everything we couldn't fit in the house or claim was destroyed by a fresh spawn with a water bucket.
This would have been annoying enough in the old world, but it is even more in the new one: why? Because of the limited time system. In the last few days I spent abount 10-15 of my initial 48 hours, and most of those hours has been wasted now. It's nonsense that a fresh spawn can destroy your entire camp, and you can't stop him in any way. It's nonsense that if you are new to the game, or not hyper-efficient, you have no way to protect your stuff for the first days of gameplay (because they can destroy the house, so don't start with the HF in front of the door, and caves are not safe anymore). While losing a few items to thiefs is part of the game, having everything destroyed for no reason, should not. And now, destroying items take no time at all! 3-4 hits and most stuff is gone! While building it, takes a lot more (just take how long it takes to chop a tree, compared to the time and stamina you need to destroy a chest or other item). Even if I had murder it wouldn't matter, because he's a fresh spawn: he has nothing to lose.
I'm fine with fresh spawns stealing, but there is a limit to it: their inventory. But when they begin destroying your stuff, or throwing everything on the ground "just because they can", that's when the game becomes annoying. And now I can't say "oh well, I'll just rebuild", because building that meant spending my account play-time, not just my personal free-time.
At this point, I either wasted most of my used play time to do stuff that I lost to a jerk, or I can start a new account and new character, losing my skill progression so far. Both options suck. And all thanks to new spawns.
In the end, what I'm saying is this: You want to limit our free time? You want us to spend money to play? Fine. But then you need to find a way to limit such behaviors. I don't know how; make it so that you can't destroy items without a mid-grade tool, or that it takes a lot more to destroy a single item.. do whatever, but do something.
