Slaves? Long story.

So the other day I was sailing around wasting time. I had come across two sea fairers chests within my travels. I ended up at shark bait cove and saw that there was a galleon and a sloop anchored. I sailed by and the sloop followed me but soon lost interest. A few minutes later I decided I was going to end the game but before that I would go back and see what the two ships were up to. It was a day after the hungering deep ended. I didbt know if they were new players or what. So I decided to sail back and either ask them if they were trying to do the meg mission and if not I was going to give them my chests and log off. However when I sailed up they proceeded to fire on my sloop. Before you know it there were six guys on my ship and they killed me. When I respawned my ship was between the galleon and sloop and they had patched my ship up. 3 guys remained on my ship, two went back to the galleon and one on the other sloop. The one pirate explained that I was now their slave and if I wanted to live I would do as the said. And if I was lucky they might give me one of my chests back haha. They were giggling like a bunch of school girls. So here was the situation. One pirate on the back of my ship looking backwards with his spy glass looking for other ships. One guy with a pistol to the back of my head and the last pirate looking at me from the stairs. They ordered me to sail NE to the closest outpost. The whole time I'm thinking how am I gonna get out of this situation. Especially being a solo pirate from day one. So here's the end result, guy is yelling at me to sail NE I told him well someone needs to lower the sails. The the pirate with the pistol to the back of my head lowers them. Once he did I steered into the galleon. Seeing there was no way to avoid it. It immediately cause 2 holes in the ship so the one pirate on the stairs went down to patch. As the pirate on the sails adjusted for the wind I quick turned off the wheel and shot him. Then I jumped onto the awning where the other pirate was looking with his spy glass and killed him. By the time the last pirate made his way up on deck from patching the holes I killed him with my sword. I screamed I'll never be a slave on my own ship and sailed away with the galleon in pursuit. They managed to fire a few guys from their cannon through the chase and a couple ended up latching onto my ladder with the end result of them being shot off. Eventually they gave up the chase. Has anyone else encountered this? Other pirates trying to enslave you?
