Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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)

ChowPandaInu.distributeAndLiquify(address,address) (#519-585) performs a multiplication on the result of a division:
-halfLiquidity = liquidityFeeCounter.div(2) (#537)
-bnbToBeAddedToLiquidity = deltaBalance.mul(halfLiquidity).div(tokenAmountToBeSwapped) (#548-550)
Consider ordering multiplication before division.
