This is smart. Ensures you have valid payment information, which implies a financial institution is running KYC on your customer. That reduces fraud and abuse while also reducing friction for real users to increase their spend within your ecosystem when a new product catches their eye.
All posts since then have come up dead, except for one about Factorio for some reason.
On a side note, Lapsa, you can test your theory about microwave transmissions fairly easily by simply going inside of a faraday cage. Simplest method I can think of is to go to the hardware/furniture store and stand in a metal storage cabinet. If you can still hear the voices, then it means they're not being transmitted from external microwaves - a microwave capable of causing the Frey Effect can't penetrate thicker metal like that unless there are gaps of ~1cm or more.
If others could please downvote this comment so that it goes to the bottom and he can see it, that would be greatly appreciated!
