> I think there's a term inside credit card companies for people like me: leeches or something like that.

that's some odd classism there.

credit card companies love your data. they can package it, sell it, analyze it.

this is real data of actual behavior, not whatever people say or click -- money where the mouth is.

even if they never make a cent off of you from an interest perspective they 1) still get fees from the merchants, and 2) get all of that juicy juicy transaction info -- and that info alone might be worth the costs.
