BuffedKabosu.swapBack() (#528-597) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountETHMarketing}() (#572-575)
- (success,None) = address(buyBackFeeReceiver).call{gas: 30000,value: amountETHBuyBack}() (#576-579)

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.

BuffedKabosu.slitherConstructorVariables() (#269-805) performs a multiplication on the result of a division:
-gonMaxWallet = TOTAL_GONS.div(100).mul(5) (#308)
Consider ordering multiplication before division.

BuffedKabosu.swapBack() (#528-597) ignores return value by router.addLiquidityETH{value: amountETHLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#588-595)
Ensure that all the return values of the function calls are used.

BuffedKabosu.totalFee (#314-315) is set pre-construction with a non-constant function or state variable:
- ecosystemFee.add(liquidityFee).add(marketingFee).add(buyBackFee)
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^0.7.4 (#4) allows old versions
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.
