What have you done to earn passive income? I am pretty good at automation / web scarping and so on. I previously wrote a algo trading bot that can trade on CFD-platforms all day long (something they normally prevent you from doing as they want you to trade manually), before that I wrote a script that plays any given strategy in online-poker automatically. Normally I would just go out to lectures and stay at the library studying while my machine at home does its stuff all day long. The profits weren't extreme but I still make passively about $100/week and its more of a learning-experience for me really.

I know that a while back there was a lot of talk on the internet about making money online, is there still a way for to make money by siting all day long and doing some boring task for marketing companies for example?, i.e. by clicking through ads or completing surveys? I can imagine that I can write a bot which can do that all day... also general thread: what have you done to earn passive income?
