MDL [Meta Decentraland] Token

MDL.swapAndDistributeBNB(uint256) (#1749-1777) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(dividendTracker).call{value: forDividends}() (#1769)
MDL.addLiquidity(uint256,uint256) (#1783-1797) sends eth to arbitrary user
Dangerous calls:
- pancakeRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp.add(300)) (#1789-1796)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

MDL.swapTokensAtAmount (#1439) is set pre-construction with a non-constant function or state variable:
- 10000 * (10 ** decimals())
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.

Pragma version^0.8.0 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6
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 MDL.swapAndDistributeBNB(uint256) (#1749-1777):
- (success) = address(marketingWallet).call{value: forMarketing}() (#1763)
- (success,None) = address(dividendTracker).call{value: forDividends}() (#1769)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
