Root Cause: The likeUser function does not update userBalances with the msg.value (1 ETH) sent by users. As a result, the ETH remains in the contract's balance but is not tracked for reward distribution.

Impact:

• Users lose their ETH as it is not allocated to their balances.

• Matches result in zero rewards being sent to the MultiSig wallet.

• ETH accumulates in the contract with no retrieval mechanism.

Recommendation:

• Update userBalances in likeUser:

  userBalances[msg.sender] += msg.value; // Add this line in the likeUser function

• Ensure fees and rewards are calculated based on tracked balances.
