TokenRecover.recoverERC20(address,uint256) (#1128-1130) ignores return value by IERC20(tokenAddress).transfer(owner(),tokenAmount) (#1129)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

Variable Ownable._owner (#1067) is not in mixedCase
Follow the Solidity naming convention.
