Dangerous calls:

CHOP.swapEthForTokens(uint256,address,address) (#1794-1807) sends eth to arbitrary user
Dangerous calls:

CHOP.addLiquidity(uint256,uint256) (#1846-1861) sends eth to arbitrary user
Dangerous calls:

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.
