Freezing feature? I'm not an expert in Ethereum - where can you see on Ethscan if assets can be freezed or not?
Put an address into item 10 here
https://etherscan.io/token/0x7f2176ceb16dcb648dc924eff617c3dc2befd30d#readContractIf true result displayed, that account is frozen already.
Frozen accounts can't send Ohni. They can still receive them. So if you send you should check to see if the account is frozen. Otherwise you might as well send to the contract owner.
No one can mine Ohni except for the contract owner.
