BDKS [Baby Doge King Son] Token

BabyDogeKingSon.swapBack() (#291-332) sends eth to arbitrary user
Dangerous calls:
- (MarketingSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#316)
- (buybackSuccess) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBbuyback}() (#318)
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.

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.

BabyDogeKingSon.takeFee(address,uint256) (#272-282) performs a multiplication on the result of a division:
-feeAmount = amount / 100 * actualFee (#276)
BabyDogeKingSon.slitherConstructorVariables() (#113-411) performs a multiplication on the result of a division:
-swapThreshold = _totalSupply / 10000 * 5 (#173)
Consider ordering multiplication before division.

BabyDogeKingSon.swapBack() (#291-332) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,marketingFeeReceiver,block.timestamp) (#322-329)
Ensure that all the return values of the function calls are used.

BabyDogeKingSon._transferFrom(address,address,uint256) (#234-257) uses timestamp for comparisons
Dangerous comparisons:
- ! launched() && recipient == pair (#247)
BabyDogeKingSon.launched() (#334-336) uses timestamp for comparisons
Dangerous comparisons:
- launchedAt != 0 (#335)
Avoid relying on block.timestamp.

BabyDogeKingSon._liqSupply (#141) is set pre-construction with a non-constant function or state variable:
- (_totalSupply - _burntSupply)
BabyDogeKingSon.buyTotalFee (#149) is set pre-construction with a non-constant function or state variable:
- buyMarketingFee + buyBuyBackFee
BabyDogeKingSon.sellTotalFee (#154) is set pre-construction with a non-constant function or state variable:
- sellMarketingFee + sellBuyBackFee + sellLpFee
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.

Pragma version^0.8.9 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.
