It's griefing provided by griefers thorough the utilisation of camping in an unintentional way.
Pure PvP players don't camp out players on their ships because there is no challenge and it doesn't provide them with the fantasy context they are after. Also the scuttling can be abused.
Here's what I would do. Following is from Reddit:
Been thinking how to mitigate frustration here. I think I found the solution that has the highest probability to fit the game as well as giving satisfaction across the board.
Issues | Shamed And Abused
- trolling via spawncamping
- wasting progression
- treasure does not interest trolls
- no PvP challenge due abused scuttling
Solution | Replacing Fantasy Context
- ferry locked ghost mode for timed scouting
- pity of the seas (wrath of the damned)
- allows players to keep onboard treasure
- overboard treasure is lost to the takers
Premise
This approach forces all PvP players to have a deadline to fetch those treasure chests they earned fair and square, but since trolls and griefers don't care about the treasure, player whose treasure it is should have a chance to keep some of their progression. However, actual scuttling sinks the ship which is an issue because sinking allows loot to float to the surface meaning the player whose ship it is will get nothing back except their ship.
Pity of The Seas / Wrath of The Damned
Replacement for the current scuttling feature. Solution is to change the fantasy context because the current one doesn't work exactly as intended; allows trolling. Therefore changing from a mere sinking ship to a maelstrom devoured ship that pops from another maelstrom elsewhere works a lot better. The ship disappears anyway, but doesn't deliver when it comes to believable immersion. However, thorough this revised context the immersion is safe and the ship doesn't sink, but is transferred elsewhere by the sea herself recognising the agony their beloved children suffer in the hands of ill-driven 'greenbeards'. Any loot that the players leave for the maelstrom to devour will be transported to the other location with the ship.
Mechanism
All the devs need is to code a maelstrom to form under the ship that is been harassed after the captain of the ship asks a favour from the ferry captain before the whole crew respawns from the ferry. This way the feature cannot be abused by players that try to avoid PvP contact while having no loot and it allows targets of harassment keep some of their progression, but also rewards quick enough players to whom loot really means something. The only ones getting nothing are the trolls and griefers whose sole purpose is to break both PvE and PvP players. Plus, in case the ship is jammed the crew can still drown in order to go to the ferry and unjam the ship. This also stays in line with some of the real behaviour pirates had. Instead of getting killed by a crew sailing under a bloody red flag, pirates often jumped overboard even if it meant certain drowning.
Cure for griefing, trolling and toxicity is to force griefers, trolls and those toxic avengers to play PvP at least like a pure PvP player. Nothing makes them feel worse than to be treated as good people.
