Nah, but I understand the error. Not a big deal.
We. Just. Plain. Don't. Keep. Any. Data. Not. Immediately. Relevant. To. The. App.
Any bad actor can easily register a throwaway, and there's no way to prevent that, without storing some seriously dangerous data, so we don't even try.
It hasn't been an issue. The incident that I mentioned, is the only one we've ever had, and I nuked it in five minutes. Even if a baddie gets in, they won't be able to do much, because we store so little data. This person would have found all those connections to be next to useless, even if I hadn't stopped them.
I'm a really cynical bastard, and I have spent my entire adult life, rubbing elbows with some of the nastiest folks on Earth. I have a fairly good handle on "thinking like a baddie."
It's very important that people who may even be somewhat inimical to our community, be allowed to register accounts. It's a way of accessing extremely important resources.
