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.

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

GoatWolf.contractSwap(uint256) (#498-553) performs a multiplication on the result of a division:
-toLiquify = ((contractTokenBalance * ratios.liquidity) / ratios.totalSwap) / 2 (#508)
-liquidityBalance = (amtBalance * toLiquify) / swapAmt (#524)
Consider ordering multiplication before division.

GoatWolf.finalizeTransfer(address,address,uint256,bool,bool,bool) (#595-620) has external calls inside a loop: antiSnipe.checkUser(from,to,amount) (#604-605)

Variable 'GoatWolf.finalizeTransfer(address,address,uint256,bool,bool,bool).check (#604)' in GoatWolf.finalizeTransfer(address,address,uint256,bool,bool,bool) (#595-620) potentially used before declaration: checked = check (#605)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

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.
