StandardToken.transfer(address,uint256) (#128-154) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#129)
StandardToken.transferFrom(address,address,uint256) (#161-186) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#162)
Remove the equality to the boolean constant.

Pragma version^0.4.24 (#1) allows old versions
solc-0.4.24 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

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.

Token seems to be untradeable: there is no PancakeSwap trading pair and no trading volumes. Ignore for presale.
