Sometimes I say [brand name] over and over just to see if my phone serves me relevant ads or spam emails afterwards. If it doesnt give me [brand name] ads, that means my privacy module settings are tuned correctly. Sometimes if I receive a remotely "relevant" spam email, I get suspicious of whatever thing I most recently downloaded.
It may be a futile endeavor to make it so that no one can steal to my information but I'll make damn sure acquiring my information is too expensive to be profitable. Make them hire better/actual hackers instead of using an automatic script.
