The only time I got a photo in DMs was when Nicole switched from text to photos.
In all seriousness, disabling Pictures in DMs will prevent Spam, Trolling and NSFL pictures that could be sent to bother people.
In my opinion, there is really no use case for pics in DMs for Lemmy.
That would be nice. Maybe as an opt-in option for users.
Opt out, would serve first time users better.
