0x2839D39F79aDBFFFC315c3ffaDdBDfFA50162833 - Honeypot - incomplete transfer logic implementation. HARD SCAM DO NOT BUY

function transferFrom(
    address from,
    address to,
    uint256 value
) external returns (bool);
}

The transferFrom function is just a declaration without an actual implementation. The code does not perform any operations.

function _transfer(
    address from,
    address to,
    uint256 amount
) internal virtual {
    require(from != address(0), "ERC20: transfer from the zero address");
    require(to != address(0), "ERC20: transfer to the zero address");

Same here, the code declare variables but does not perform any operations on them which is not sufficient for the transfer logic to be successfully completed.
