Since people seem to be way to unintelligent to understand the difference between the two (either they have not actually played the game, or are to stupid to spend 10 minutes to actually think about the issues) I will try to break it down for you.
Trolling: The use of low-resource items for the SOLE purpose of annoying (griefing) players. This primarily includes abusing the mechanics of the game in order to wall off peoples houses and essentially box them in their own house, without giving the person in the house any ability to stop you. I’m not talking about the equivalence of building a fence around their house. I’m talking about the equivalence of someone walking to your front door. And pouring concrete directly in front of your doors and windows.
Raiding: The use of high-resource items (grenades/explosives) to tactfully gain entry into a persons house/building in order to try to a) take ownership of the house, or b) steal all of their loot. This is a very legitimate part of the game and gives the owner of the house every opportunity to defend his base due to the nature of how long it takes to break down doors/walls.
Trolling is NOT ok for the longevity of this game.
Raiding is perfectly fine, and is one of the MAIN attractions for this game.
Now can we finally have a constructive discussion on how to eliminate or at the least limit the amount of trolling that is currently possible in this stage of the game? Because with the recent updates, I don’t think the developers have a very clear plan to do so, unless they have some grande idea in mind that is taking a while to develop in which case, a statement would be nice so players wouldn’t have to worry about it anymore.
