It wasn't meant in a negative context - simply that players, given the time to do so, will test the defenses of a base until they find a weakness they can exploit. It may be lack of turret coverage in a particular area, or a weakness to a certain type of weapon. Without any defending players to counter such attempts, PVP'ers have all the time in the world to figure out how to solve the puzzle.
I've been observing this behavior a lot in Conan: Exiles lately. Bases don't have any form of invulnerability in that game. You have to rely on the sturdiness of the structure and the NPC's you have protecting it in your absence. NPC's are no match for players once they know the limitations of their AI, and a fortress is only as strong as its weakest link. My friends built a walled fort on top of a mesa and felt they had strong defenses for its entrance. In their absence, another group built a bridge from another nearby mesa over to their back wall and broke through. I shouldn't say "in their absence" because a player's avatar lies "sleeping" on the ground while the player is offline. Of the five friends I had playing the game, they have all quit after returning to the game each day and finding their looted base and corpses.
