BluePuliInu.addLiquidity(uint256,uint256) (#1521-1533) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1524-1531)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract ticker (Blue Puli) 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.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
