I think what you are doing is riding a fine line between legal and illegal and it's not worth it. Even if you are getting free internet, you are essentially becoming a reseller by sharing your internet with various unknown people. How would you even report your income from this. I'm no lawyer or computer genius and I don't even know what I'm talking about most of the time. What I do know is this sounds kinda shady and risky in multiple ways. Go find some other way of making a few bucks that's simpler to wrap your head around. I mean no disrespect by these comments just putting in my two cents. Food for thought.
