BABYCORGI [BABY CORGI] Token

BABYCORGI.addLiquidity(uint256,uint256) (#1640-1654) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#1645-1652)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BABYCORGI.swapAndSendToFee(uint256) (#1570-1578) ignores return value by IERC20(FIL).transfer(buyBackWallet,newBalance) (#1576)

Contract locking ether found:
Contract BABYCORGIDividendTracker (#1668-1874) has payable functions:
- DividendPayingToken.receive() (#569-571)
- DividendPayingToken.distributeDividends() (#586-597)
- DividendPayingTokenInterface.distributeDividends() (#483)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

BABYCORGI.setSellFeeIncreaseFactor(uint256) (#1389-1392) contains a tautology or contradiction:
- require(bool,string)(sellFeeIncreaseFactor >= 0 && sellFeeIncreaseFactor <= 50,BABYCORGI: Sell transaction increase must be between 0 and 50) (#1390)
Fix the incorrect comparison by changing the value type or the comparison.
