McYeezus.swapBack() (#328-369) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#353)
- (charitySuccess) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBcharity}() (#355)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

McYeezus.slitherConstructorVariables() (#184-453) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 1000 * 3 (#220)
Consider ordering multiplication before division.

McYeezus.swapBack() (#328-369) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,marketingFeeReceiver,block.timestamp) (#359-366)
Ensure that all the return values of the function calls are used.

- marketingFee = _marketingFee (#413)
- totalFee = _liquidityFee.add(_buybackFee).add(_marketingFee) (#414)
- feeDenominator = _feeDenominator (#415)
Emit an event for critical parameter changes.

McYeezus.buyTokens(uint256,address) (#371-382) is never used and should be removed
Remove unused functions.

Additional information: link

McYeezus._maxTxAmount (#196) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 2) / 100
McYeezus._maxWalletSize (#197) is set pre-construction with a non-constant function or state variable:
- (_totalSupply * 4) / 100
McYeezus.swapThreshold (#220) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1000 * 3
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 McYeezus.swapBack() (#328-369):
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#353)
- (charitySuccess) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBcharity}() (#355)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
