MEALS.swapBack() (#567-606) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#592)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

Contract ownership is not renounced (belongs to a wallet)

Contract has 11% buy tax and 11% sell tax.
Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d PancakeSwap volume is less than $100. Token is either dead or inactive.

Average 30d number of PancakeSwap swaps is less than 1. Token is either dead or inactive.

Average PancakeSwap trading volume, liqudity, number of swaps are extremely low. Token seems to be dead.

Swap operations require suspiciously high gas. Contract logic is complex and may disguise some form of scam.

Average 30d PancakeSwap liquidity is low.

Token is deployed only at one blockchain

Token has only one trading pair

Token was delisted (assigned to inactive / untracked listing) from CoinMarketCap

Token is not listed at Mobula.Finance

Additional information: link

Token has no active CoinMarketCap listing / rank

Token has a considerable age, but social accounts / website are missing or have few users

Token has a considerable age, but average PancakeSwap 30d trading volume is low

Token has relatively low CoinGecko rank

Young tokens have high risks of price dump / death
