I haven’t had a problem, but all my accounts (including my email account) are secured with 2 Factor Authentication
My understanding is that Team Security will attempt recovery but, in a game with a player driven economy, it isn’t as simple as creating new stuff for you. - it will take time to trace and reverse the transactions.
Do secure your accounts - passwords aren’t sufficient. This is particularly true of your email account - which is the vector for most hacks.
