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.

MetaHooligans.swapTokens(uint256) (#758-767) performs a multiplication on the result of a division:
-transferToAddressETH(marketingWallet,transferredBalance.div(_liquidityFee).mul(marketingDivisor)) (#765)
