How do you get your account back if it's been hacked?

[Pudges]

I was wondering if SL developers could help get an account back to the original owner if it has been hacked. I remember the account name and security question, but they changed emails.

Welcome to Second Life Answers, Pudges

The moment anyone discovers or suspects their account has been hacked, they should contact LL Support.

LL will then stop access to the account and investigate further. 

More information can be found on the Official Knowledge Base.
