Sporty.swapBack() (#380-433) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#407)
- (success,None) = address(SportyInsurancePoolFeeReceiver).call{gas: 30000,value: amountSportyInsurancePool}() (#408)
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.


Contract ownership is not renounced (belongs to a wallet)

Contract ticker (SPƆRTY) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Pragma version^0.8.15 (#30) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.15 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.

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