SPB [SPORTSBETTING] Token

SPORTSBETTING.contractSwap(uint256) (#672-706) sends eth to arbitrary user
Dangerous calls:
- reflector.load{value: rewardsBalance}() (#700)
- (success,None) = _taxWallets.marketing.call{gas: 35000,value: marketingBalance}() (#704)
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.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ownership is not renounced (belongs to a wallet)

Token seems to be untradeable: there is no PancakeSwap trading pair and no trading volumes. Ignore for presale.

Number of Binance Smart Chain (BSC) token holders is less than 100. Token is either dead or inactive. Ignore for presale.

Unable to find website, listings and other project-related information

Young tokens have high risks of scam / price dump / death

Token has no active CoinGecko listing / rank

Token has no active CoinMarketCap listing / rank

Token is relatively young, but twitter if very old (probably it's fake).
