I've been getting and registering those Boost sim cards that make you an actual small profit.
However, I do have a bit of a concern in terms of doing this moving forward. Although this may offend a lot of people, it is a fairly established fact that those who think critically are aware of: the Australian government and its institutions can be quite authoritarian in dealing with its citizens.
To this end, I am concerned about being put on some watch list and maybe being surveilled due to activating too many sim cards. Did anyone else think of this/analysed this?
You probably are already, but you're more likely to get into trouble with Boost (and / or what I assume to be a cashback service) for breaking their terms of service.
No you're definitely the first person in the world to worry this.
