Contract creator is blacklisted for the past scams

CoinGeckoToken.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.

Additional information: link

CoinGeckoToken.swapTokenForTokens(address,address,uint256) (#724-727) ignores return value by tokenC.transfer(account,amount) (#726)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
