Dev had already posted on
https://twitter.com/PRVirtualCoinwhich provides sufficient evidence & now all users are left without wallet updates. Dev send message to theymos, but no response.
As far as I can see there's only a message stating that the account has been hacked and they have sent a message to theymos. Not really sufficient evidence. If the account has been hacked and the email address it's good from the point of view of theymos that the twitter might be compromised too.
Only a Bitcoin address with a signed message will get the account back.
