ErrolMusk [Father Of Elon] Token

FatherOfElon.swapBack() (#309-339) sends eth to arbitrary user
Dangerous calls:
- (devSucess) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#333)
- (marketingSucess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#335)
- (liquiditySucess) = address(liquidityFeeReceiver).call{gas: 30000,value: amountBNBLiquidity}() (#337)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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 ownership is not renounced (belongs to a wallet)

-feeAmount = amount / 100 * totalFee (#297)
FatherOfElon.takeFee(uint256) (#296-300) performs a multiplication on the result of a division:
