So what? The world is more trustworthy than you can imagine. I have bought over 30 GPUs over the internet, sight unseen. From around the world and every single one has arrived good. I have also gotten over 20 from marketplace and the same. Use your common sense, from conversation and everything else, you can often separate the scammers from real folks.

It's not like buying random stuff that you can inspect!

You have no way to verify that your data is not sold to someone else, send to the provider you think, or the response is genuine and not full of prompt injections or other stuff!
