MeMeAl.claimStuckTokens(address) (#623-632) ignores return value by ERC20token.transfer(msg.sender,balance) (#631)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Pragma version0.8.17 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.17 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) (#258-267):

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