CToger [CryptogerClub] Token

CryptogerClub.sendETHToFee(uint256) (#294-297) sends eth to arbitrary user
Dangerous calls:
- _developmentAddress.transfer(amount.div(2)) (#295)
- _marketingAddress.transfer(amount.div(2)) (#296)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CryptogerClub.rescueForeignTokens(address,address,uint256) (#304-307) ignores return value by Token(_tokenAddr).transfer(_to,_amount) (#306)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract creator or owner is blacklisted for past scams

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

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.
