REC [RecoveryDAO] Token

REC.swapAndLiquify(uint256) (#654-669) ignores return value by _usdt.transferFrom(address(_tokenDistributor),address(this),newBalance) (#665)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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

Contract locking ether found:
Contract REC (#407-746) has payable functions:
- REC.receive() (#582)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.
