WORLD Token

Contract ownership is not renounced (belongs to a wallet)

WorldToken.allowance(address,address)._owner (contracts/WorldToken.sol#125) shadows:
- Ownable._owner (@openzeppelin/contracts/access/Ownable.sol#19) (state variable)
WorldToken._approve(address,address,uint256)._owner (contracts/WorldToken.sol#238) shadows:
- Ownable._owner (@openzeppelin/contracts/access/Ownable.sol#19) (state variable)
Rename the local variables that shadow another component.

WorldToken.totalTaxAlloc (contracts/WorldToken.sol#74) is set pre-construction with a non-constant function or state variable:
- marketingTaxAlloc.add(holderTaxAlloc).add(lpTaxAlloc).add(merchantTaxAlloc)
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.

Contract has 3% buy tax and 2% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Average 30d number of PancakeSwap swaps is low.

Token is not listed at Mobula.Finance
