@delta but it's possible to block users from contacting us right? In which scenario could it be an issue if some malicious trollers get a way to contact us to our regular deltachat account?
Same for qrcode we share, it's possible to invalidate them later on, preventing a leak to create such issues right?

@nextcloud I'll add those to the list: Newpipe, Delta Chat, Tusky, Tasks, OSMAnd... and of course the Nextcloud apps like the main sync client, News, Talk and more
