Wouldn't any platform have the same problem though? A forum would partition the community between those willing to make an account and submit private information and those who aren't. It seems like no matter what platform you choose there will always be those who are willing to participate and those who are not.
Not quite. Discord is a lot more invasive with their info collection than, let's say Github or Matrix servers. Second, the info posted to Github is accessible without account, which is not true of Discord.
