report
Token seems to be a scam (type: unclassified scam).


Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

CumGirl.swapBack() (#538-582) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(mFR).call{gas: gass,value: amountBNBMarketing}() (#566)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

DividendDistributor.distributeDividend(address) (#281-292) ignores return value by CAKE.transfer(shareholder,amount) (#287)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

CumGirl.launchedAt (#357) is never initialized. It is used in:
- CumGirl.getTF(bool) (#489-493)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

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


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.
