FANTASYFOX.addLiquidity(uint256,uint256) (#977-990) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#982-989)
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.

FANTASYFOX._transfer(address,address,uint256).marketingAmount (#900) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

FANTASYFOX.addLiquidity(uint256,uint256) (#977-990) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#982-989)
Ensure that all the return values of the function calls are used.

FANTASYFOX._approve(address,address,uint256).owner (#1006) shadows:
- Ownable.owner() (#152-154) (function)
Rename the local variables that shadow another component.

- numTokensSellToAddToLiquidity = val (#651)
Emit an event for critical parameter changes.

Variable IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (#326) is too similar to IUniswapV2Router01.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (#327)
Prevent variables from having similar names.

FANTASYFOX.constructor() (#584-614) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 100000000 * (10 ** 18) (#611)
Use: Ether suffix, Time suffix, or The scientific notation
