I did years ago. Went back after learning of the spoopiness and deleted my account which includes disposing of your sample and conducting no more research. Is it enough? I don't know. Will they actually discard the sample and remove my identifying info from their rolls? Probably not but who knows? It's the best I could do.
Interesting but not really a ghost ship. Read on Fox earlier today there were rough seas/weather last week and the tow cables broke. The tug was found about 50 miles away from where the ship was found the next day or two later. It was headed for a ship breaking facility. Weird part is the ship was only built on 2001, why would they be destroying it already?
