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.

Freedom.addLiquidity(uint256,uint256) (#963-976) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,blackHole,block.timestamp) (#968-975)
Ensure that all the return values of the function calls are used.

Freedom._approve(address,address,uint256).owner (#869) shadows:
- Ownable.owner() (#411-413) (function)
Rename the local variables that shadow another component.

Freedom.setUniswapPair(address).pair (#758) lacks a zero-check on :
- uniswapV2Pair = pair (#760)
Check that the address is not zero.

Ownable.unlock() (#458-463) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#460)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#356-377) uses assembly
- INLINE ASM (#369-372)
Do not use evm assembly.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#224-227) is never used and should be removed
Remove unused functions.

Additional information: link

Freedom.numTokensSellToAddToLiquidity (#701) is set pre-construction with a non-constant function or state variable:
- 5000 * 10 ** 4 * 10 ** uint256(_decimals)
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#356-377):
- (success,returndata) = target.call{value: weiValue}(data) (#360)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable Freedom.Busd (#709) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#236)" inContext (#230-239)
Remove redundant statements if they congest code but offer no value.

Variable Freedom._getRValues(uint256,uint256,uint256,uint256).rTransferAmount (#836) is too similar to Freedom._transferStandard(address,address,uint256).tTransferAmount (#989)
Prevent variables from having similar names.

Freedom.slitherConstructorConstantVariables() (#677-1018) uses literals with too many digits:
- burntReceiver = 0x0000000000000000000000000000000000000000 (#706)
Use: Ether suffix, Time suffix, or The scientific notation

Freedom.treasureReceiver (#705) is never used in Freedom (#677-1018)
Remove unused state variables.

Additional information: link

Freedom.treasureReceiver (#705) should be constant
Add the constant attributes to state variables that never change.

setBN(uint256) should be declared external:
- Freedom.setBN(uint256) (#877-880)
Use the external attribute for functions never called from the contract.
