Contract ticker ($BROKE) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

McBroke.openTrading() (#266-278) ignores return value by uniswapV2Router.addLiquidityETH{value: address(this).balance}(address(this),balanceOf(address(this)),0,0,owner(),block.timestamp) (#272)
McBroke.openTrading() (#266-278) ignores return value by IERC20(uniswapV2Pair).approve(address(uniswapV2Router),type()(uint256).max) (#277)
Ensure that all the return values of the function calls are used.
