Password was compromised months back, banned recently

Hello,
As the title says, the password and account information was compromised recently, I don't know what caused it, but I've since changed every account where I have that password and the password to my Nostalrius account has never been written anywhere besides on your servers, it's purely in my head.
I'm assuming this is why the account was banned, since I spoke to friends in-game that said I was online when I know I wasn't, but nothing was missing and nothing seemed weird, so I assumed that I was safe changing passwords to everything that could be possibly related, as well as cleaning my computer and enabling 2 factor authentication wherever possible.
Could I receive some more information on why my account is banned or if that's not possible provide me with some information regarding who gained access (like IP logs) so that I can track down the issue?
Cheers
