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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#358-379):
- (success,returndata) = target.call{value: weiValue}(data) (#362)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
