Before an instance does something malicious, how do you know it will be malicious?

Even if everyone there running it, & participating is pure of heart, how can you be assured that haXXors won’t simply break in to take advantage of that trust you’ve given them?

Banning bad instances is a reactive stance that only applies after damage has been done. Can you convince the corporate overlords to take that risk? And it only increases as the fediverse gets more popular, and more instances get trusted.

Yes and no.

Decentralized IDs exist, but will almost never be accepted by any large reputable institution.

Why trust every indie site to be 100% truthful, and definitely not full of malicious haXXors?
