Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract locking ether found:
Contract DividendDistributor (contracts/DividendDistributor.sol#24-257) has payable functions:
- DividendDistributor.receive() (contracts/DividendDistributor.sol#76)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
