Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

MemeNFT.addLiquidity(uint256,uint256) (#659-672) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#664-671)
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.


Contract ownership is not renounced (belongs to a wallet)

MemeNFT._decimals (#419) should be constant
MemeNFT._name (#417) should be constant
MemeNFT._symbol (#418) should be constant
MemeNFT._tTotal (#413) should be constant
Add the constant attributes to state variables that never change.
