I'm much more worried about discord collecting this info and selling it, or building models on it, or just giving open access to the feds. This is just some person scraping 'public' chats.

Also You can't have discord delete your messages if you're in another chat with a discord bridge. You need to have a discord account associated with messages and since you aren't logged into discord there is no recourse.

Blows my mind how some 'privacy' chats have discord, telegram, etc bridges that constantly feeding them data. Looking at you GrapheneOS.
