TigerShinobi.swapBack() (#390-432) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#415)
- (success2) = address(giveawayReceiver).call{gas: 30000,value: amountBNBGiveaway}() (#416)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Token is flagged by TokenSniffer due to presence of exploit in contract code


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.

TigerShinobi.swapBack() (#390-432) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#420-427)
Ensure that all the return values of the function calls are used.

TigerShinobi._symbol (#241) should be constant
TigerShinobi._totalSupply (#244) should be constant
TigerShinobi.charityFee (#259) should be constant
TigerShinobi.devFee (#260) should be constant
Add the constant attributes to state variables that never change.

renounceOwnership() should be declared external:

Pragma version^0.8.11 (#4) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in TigerShinobi.swapBack() (#390-432):

Low level call in TigerShinobi.clearBalance() (#509-512):

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
