QD [QilinDao] Token

QilinDao.sendETHToFee(uint256) (#399-402) sends eth to arbitrary user
Dangerous calls:
- _developmentAddress.transfer(amount.div(2)) (#400)
- _marketingAddress.transfer(amount.div(2)) (#401)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

QilinDao.rescueForeignTokens(address,address,uint256) (#418-429) ignores return value by Token(_tokenAddr).transfer(_to,_amount) (#428)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

Combination 2: Unchecked transfer + 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.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
