MyFlokiValentine.clearStuckBalance() (#337-340) sends eth to arbitrary user
Dangerous calls:
- (sent) = address(owner).call{value: (address(this).balance)}() (#338)
MyFlokiValentine.swapBack() (#385-429) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#412)
- (tmpSuccess,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#413)
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.

Contract ticker ($MFLV) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

MyFlokiValentine.takeFee(address,uint256,bool) (#354-367) performs a multiplication on the result of a division:
-feeAmount = amount.div(feeDenominator * 100).mul(totalFee).mul(multiplier) (#361)
Consider ordering multiplication before division.

MyFlokiValentine.swapBack() (#385-429) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#419-426)
Ensure that all the return values of the function calls are used.

MyFlokiValentine._transferFrom(address,address,uint256) (#297-328) uses timestamp for comparisons
Dangerous comparisons:

MyFlokiValentine.totalFee (#210) is set pre-construction with a non-constant function or state variable:
- marketingFee + liquidityFee + devFee
MyFlokiValentine.swapThreshold (#234) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 500
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.

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.
