Freshgainstein.swapBack() (Contract.sol#300-341) sends eth to arbitrary user
Dangerous calls:
- distributor.deposit{value: amountBNBReflection}() (Contract.sol#327)
- address(marketingFeeReceiver).transfer(amountBNBMarketing) (Contract.sol#328)
- router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (Contract.sol#331-338)
Freshgainstein.buyTokens(uint256,address) (Contract.sol#370-381) sends eth to arbitrary user
Dangerous calls:
- router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,to,block.timestamp) (Contract.sol#375-380)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Freshgainstein._getPriceImpact(uint256) (Contract.sol#238-253) uses a dangerous strict equality:

Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

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.

Combination 2: Unchecked transfer + 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.

Freshgainstein.swapThreshold (Contract.sol#80) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1000
Freshgainstein._maxTxAmount (Contract.sol#81) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 99
Freshgainstein.maxWalletSize (Contract.sol#82) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 49
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.
