PEACH [Darling Waifu Peach] Token

Peach._autoSwap(address,uint256) (#679-694) uses a weak PRNG: "stabilizer = stabilizers[uint256(keccak256(bytes)(abi.encodePacked(block.timestamp))) % stabilizers.length] (#682-685)"
Do not use block.timestamp, now or blockhash as a source of randomness

Peach._getCustomPriceAndCommision(address,address,uint256) (#587-657) performs a multiplication on the result of a division:
-_commission = _amount.mul(_commission).div(100000) (#622)
-_commission = _amount.div(100) (#633)
Consider ordering multiplication before division.
