I read an AI answer, nod along, and move on. Ten minutes later, if someone asked me to explain it, I couldn't.

For a while I told myself that was fine. The problem got solved, which is what I came for. But some answers I actually wanted to keep, and for those, nodding along wasn't enough.

So I built something into bubbling. Once you've read the answer, you tap a button and it folds away, leaving an empty box. You write down what you understood, in your own words. Closed-book review, basically.

It's harder than it sounds. But the places where I got stuck turned out to be exactly the parts I'd skipped over the ones I was sure I'd understood while reading.

We launched a SaaS recently and noticed a cluster of accounts created within minutes of each other that never confirmed email or returned after signup. We want to keep our user table healthy without accidentally deleting real users.

Curious what other founders do in practice, more specifically:

• Do you auto-delete accounts after X days without email confirmation? If so, what timeframe worked for you?

• Do you keep soft-deleted rows for analytics or GDPR reasons? Any retention windows you recommend?

• If you have automated detection, what signals did you use (IP clusters; identical metadata; signup rate spikes)?

We know this situation exists, but not many people are openly talking about it.

Being in a highly competitive entrepreneurial environment is challenging on many levels... not only in terms of sales and business growth, but also legal responsibilities, administration, and often handling most things independently, all while managing family and personal stuff.
