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.

FeedEveryShiba.addLiquidity(uint256,uint256) (#892-908) uses timestamp for comparisons
Dangerous comparisons:
- ethAmount - ethFromLiquidity > 0 (#906)
Avoid relying on block.timestamp.

solc-0.8.6 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.

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
