Could it be they have decided to start staking user balances and cannot process withdrawals, so the wallet is locked instead..? Seems likely in the current scenario

Stay tuned to http://blog.freestaking.com this weekend - I have a feeling a post about their current situation may pop up there soon  

Will unlock as needed for updates; no need for discussion today

Less than 12 hours after that blog post, they have suddenly, after two weeks, opened wallet for withdraws and delisted coin immediately

The fuckery is strong. User beware
