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’m not 100% in the loop on things they’ve done, but I think the main thing is that there are better alternatives out there such as Signal for keeping in touch with friends and family, but oftentimes those friends/family just don’t want to have yet another messaging app so it leaves you needing Discord to keep in touch.
