SAFU [SaFuTrendz] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

SaFuTrendz.clearStuckBNB() (#982-984) sends eth to arbitrary user
Dangerous calls:
- address(marketingAddress).transfer(address(this).balance) (#983)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SaFuTrendz.tradingActiveBlock (#442) is never initialized. It is used in:
- SaFuTrendz._transfer(address,address,uint256) (#646-690)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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.

SaFuTrendz._rTotal (#412) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))

SaFuTrendz._previousMarketingFee (#423) is set pre-construction with a non-constant function or state variable:
- _marketingFee
SaFuTrendz._maxTxAmount (#432) is set pre-construction with a non-constant function or state variable:
- (_tTotal * maxTxPercent) / maxTxDivisor
SaFuTrendz._maxTxAmountUI (#433) is set pre-construction with a non-constant function or state variable:
- _maxTxAmount
SaFuTrendz._previousMaxTxAmount (#434) is set pre-construction with a non-constant function or state variable:

SaFuTrendz.pubTokensSellToAddToLiquidity (#437) is set pre-construction with a non-constant function or state variable:
- numTokensSellToAddToLiquidity
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
