BabySharkGirl.addLiquidity(uint256,uint256) (#1138-1148) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityAddress,block.timestamp) (#1140-1147)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Ownable._lockTime (#218) is never initialized. It is used in:

Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

BabySharkGirl._transfer(address,address,uint256) (#996-1086) uses a dangerous strict equality:
- from != owner() && to != uniswapV2Pair && block.number == tradingActiveBlock (#1018)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

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.

Not a direct threat, but may indicate unreliable intentions of developer. Both name and ticker of current token are widespread, i.e. common across multiple tokens. This is slightly suspicious
