MKI.swapAndLiquify(uint256) (#1027-1060) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(marketingEthShare) (#1057)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Additional information: link

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)

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

MKI.takeBuyback(address,uint256,uint256,uint256) (#1156-1167) performs a multiplication on the result of a division:
-tBuyback = tAmount.div(100).mul(_buybackFee) (#1160)
MKI.takeMarketing(address,uint256,uint256,uint256) (#1169-1180) performs a multiplication on the result of a division:
-tMarketing = tAmount.div(100).mul(_marketingFee) (#1173)
Consider ordering multiplication before division.

Pragma version0.8.13 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.13 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.
