It's Leon (John Goldloather). I just wanted to say I'm sorry for what happened to your account, and that I had absolutely nothing to do with it. I did, in fact, delete John Goldloather, but I did not use the pirate that took control of Mark. That was an imposter.
I have a few tips for restoring your account back to normal. Disney may not have done this already.
If he deleted any Pirates, you can get them restored as long as they were deleted under 7 days ago. So if you're missing some pirates, don't delay in contacting Disney.
This one is a bit more controversial. If you're missing a lot of items in your inventory, ask Pirates to "Revert my account's progress back to DD/MM/YY". Tell them that and it should restore all of the items that were deleted. I've seen them help some people with this, but not all.
If you have any more questions, feel free to reply to this thread, and I'll respond as soon as I can.
