LearnToEarn.collectBNB() (#612-614) sends eth to arbitrary user
Dangerous calls:
- address(operator()).transfer(address(this).balance) (#613)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

LearnToEarn.collectToken(address) (#605-607) ignores return value by IBEP20(contractAddr).transfer(operator(),IBEP20(contractAddr).balanceOf(address(this))) (#606)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Contract ownership is not renounced (belongs to a wallet)
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.
LearnToEarn.allowance(address,address).owner (#438) shadows:
- Ownable.owner() (#302-304) (function)
LearnToEarn._approve(address,address,uint256).owner (#582) shadows:
- Ownable.owner() (#302-304) (function)
Rename the local variables that shadow another component.

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.
