SquidX456.addLiquidity(uint256,uint256) (#1474-1489) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1480-1487)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SquidX456.swapAndSendToBBFee(uint256) (#1394-1401) ignores return value by ERC20(BUSD).transfer(_buyBackWalletAddress,newBalance) (#1400)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

SquidX456.setMaxWalletPermille(uint8) (#1289-1294) contains a tautology or contradiction:
- require(bool,string)(maxWalletPermille >= 5 && maxWalletPermille <= 1000,ZomZilla: The max wallet percentage must be between 0.5% (5) and 100% (1000)) (#1290)
Fix the incorrect comparison by changing the value type or the comparison.

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.
