IslandBoyz.takeTeam(address,uint256,uint256,uint256) (#1176-1187) performs a multiplication on the result of a division:
-tTeam = tAmount.div(100).mul(_teamFee) (#1180)
Consider ordering multiplication before division.

IslandBoyz._transfer(address,address,uint256) (#988-1027) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(cooldown[to] < block.timestamp) (#1001)
Avoid relying on block.timestamp.

Remove unused functions.

Additional information: link

IslandBoyz._previousTeamFee (#724) is set pre-construction with a non-constant function or state variable:
- _teamFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.7 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 Address._functionCallWithValue(address,bytes,uint256,string) (#444-465):
- (success,returndata) = target.call{value: weiValue}(data) (#448)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable IslandBoyz._maxTxAmount (#733) is not in mixedCase
Follow the Solidity naming convention.

IslandBoyz.slitherConstructorVariables() (#680-1268) uses literals with too many digits:
- _maxTxAmount = 1000000000000000 * 10 ** 9 (#733)
Use: Ether suffix, Time suffix, or The scientific notation

setSwapAndLiquifyEnabled(bool) should be declared external:
- IslandBoyz.setSwapAndLiquifyEnabled(bool) (#1262-1265)
Use the external attribute for functions never called from the contract.
