PPOLL [PancakePoll] Token

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

PancakePoll.swapAndLiquify(uint256) (#1903-1958) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(buyBackWallet).call{value: buyBackBalance}() (#1952)
PancakePoll.sendToOperationsWallet(uint256) (#2014-2016) sends eth to arbitrary user
Dangerous calls:
- address(operationsWallet).transfer(amount) (#2015)
PancakePoll.addLiquidity(uint256,uint256) (#1981-1996) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#1987-1994)
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.

PancakePoll._transfer(address,address,uint256) (#1772-1901) uses a dangerous strict equality:
- _holderLastSellDate[to] == block.timestamp (#1808)
PancakePoll.getHolderSellFactor(address) (#1604-1620) uses a dangerous strict equality:
- _holderLastSellDate[holder] == 0 (#1609)
Don't use strict equality to determine if an account has enough Ether or tokens.

Pragma version^0.8.9 (#13) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Contract has 10% buy tax and 19% sell tax.
Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Token is deployed only at one blockchain

Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.

Average 30d PancakeSwap volume is low.

Average 30d number of PancakeSwap swaps is low.

Average PancakeSwap trading volume, liqudity, number of swaps are low. Token seems to be inactive.
