AFFINITY [SafeAffinity] Token

SafeAffinity.reflectAndDistribute() (SafeAffinity.sol#267-289) sends eth to arbitrary user
Dangerous calls:
- (successful,None) = address(marketingFeeReceiver).call{gas: 26000,value: amountBNBMarketing}() (SafeAffinity.sol#280)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

SafeAffinity.reflectAndDistribute().amountBNBMarketing (SafeAffinity.sol#270) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

- (successful,None) = address(marketingFeeReceiver).call{gas: 26000,value: amountBNBMarketing}() (SafeAffinity.sol#280)
- (success,None) = address(address(distributor)).call{gas: 26000,value: amountBNBReflection}() (SafeAffinity.sol#285)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
