Running favor bank
Acknowledge that networking involves the reciprocal exchange of favors. Keep helping others out and making deposits to your favor bank. Be generous with your favors before you expect to see them being returned. Do not expect a few minor favors on your part to reap large paybacks immediately. Play a long game. Never talk explicitly about the favors you are banking. Don't allow anyone to take advantage of you. This is a one-sided situation you need to stop immediately. Some are looking for a genuine friendship and connection. However, many just be seeking out someone to dump the bulk of their work on or help cover for them when they make mistakes.
