was trying out the grok free trial and noticed something interesting around how they use payment methods like UPI
reported it and they marked it as informative, which is fair
it made me think that "one trial per user" is actually hard to enforce if you rely on something like UPI as identity
works great for payments, not always as a strong identity signal
feels like a tradeoff between keeping things easy to use and preventing abuse
curious how others here think about this, especially since UPI is everywhere in india
