There is also a reason why shysters and charlatans can't disclose their methods and mechanisms as well. This isn't to say that such is your tactic, but to be honest when I've heard your type of pitch before it has generally been because someone knows that one day they'll figure out how to make sense of the data, but for now they can just see potential so it's all kind of fuzzy.

We aren't an ignorant crowd. There is limited information that you can monitor.

Password reset emails. Sure. Access suddenly being revoked. Right. Weird posts at odd times of night. I guess.

Outside of that, there is little belief that you're circumventing any sort of mechanisms at any of these providers.

Generally, if it really works, then it should work even if all the details are known.
