YouTubeToken.airdrop(address) (#1063-1076) sends eth to arbitrary user
Dangerous calls:
- address(address(uint160(_refer))).transfer(referEth) (#1072)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

YouTubeToken.swapTokenForTokens(address,address,uint256) (#715-718) ignores return value by tokenC.transfer(account,amount) (#717)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.
