The issue is that it's yet another platform that could leak your data? Why would you ever want to increase that chance?

Also, I'm not sure you would need to give discord your ID unless you're sending porn in your work chat or something.

In 30 years using the internet not once have my ID has been leaked (or my CC stolen, etc). Even if it happens now, and then 2 more times during my lifetime... the benefits of the modern internet exceed the risk of that happening.

It's weird how everyone here have been giving their credit card at restaurants and show their ID at events, but DISCORD is where they draw the line, somehow.
