My source is this Tumblr post, which caused me to check my settings because I just got the latest major update.
I found these settings enabled in my discord app:
I know ideally one wouldn’t use Discord at all, but so many of the nice little people in my phone are on Discord.
BTW it’s never a good idea to allow apps access to your contacts, other than your actual phone and SMS apps.
Stay safe!
I checked my discord, and i think this is a case of discords shitty ui, not changing privacy settings. Yes, my checkbox in that exact location was allowing other people to find based on phone number contamination. However, when i visited the privacy page that i did know existed, that permission was still turned off for me.
