probably won’t be hard to spot all the accounts that sign up en masse, send 3 data points then stop forever because they got bored or forgot.

Alright, sure. The company will rigorously dig through the data to exactly remove exactly the specific accounts that aren’t real and deftly deal with it, and it won’t be some intern with a weeks training in paper docs from three years ago. No, it’ll be people who will know to do exactly those things. And the data you’re scraping to sell, well, no-one will mind you splicing out data you claim isn’t real and was fake, no they’ll be fine with that. Then when that intern is gone–and they didn’t log anything because they were never taught to–and the new intern arrives, they’ll know to continue exactly where they should, and at no point will anyone fuck up the dates, times, or additions from previous months. At each and every stage exactly what has to happen will happen, and no code changes, updates, or manager-directives will change any of these parts in any way. The addition of anywhere from dozens to hundreds to even tens of thousands of new accounts will be easy to deal with, because this has all been prepared ahead of time, and will immediately be dealt with. It won’t take weeks of meetings on how to tackle it, by whom, and what to push back - because they use waterfall/agile, and it’s a foolproof system where you don’t just punt things forward, you deliberately and delicately lay out each and every change that will now take place mixed with the 2 years that have already been planned out.

Absolutely everything will be covered and not a single thing will get through, and they’ll carefully and easily parse through the data with zero issues on the demand of a very competent government that doesn’t show any signs of issue whatsoever.
