Any recent hacked accounts from Southperry users?

I really wish I knew my birthday and my last name for this account.

Do what Hiep said above. As for birthday, you're basically screwed unless you use a Bday cracker.

Or this for last name:
1. Go to Events page
2. Click any event
3. Scroll down to where you see a place to enter an Email and name
4. Enter your own email and any name and send
5. When you receive the email, it will say your first and last name you used to sign-up with.

This really is the last straw for me. I did everything right, never shared info, never went to sites

Unfortunately, Nexon gives everyone a Maple Tip in game that says you should choose your password carefully with numbers and letters, and change it periodically. If you haven't been hacked yet, and haven't changed your pass in the last week or so, go change it now.
