Some accounts are stolen recently.



If you care a lot about your account, change your password. Do not use the same password on other sites if possible.
If your account was used to sell invites, cheat or do something violating our rules, we will punish that account regardless of who is really using it.
REMEMBER: You own your account. It's your responsibility to secure it.

Invite system is temporarily closed. Will re-open after some upcoming security updates.
