I think that’s a wise approach, it’s too early with people adopting new platforms. I do like @Melon 's idea of suggesting photo-only posts come with some context, or insight into the post. Especially if folks happen to be sharing other work that isn’t their own, but that’s another topic altogether. I doubt we’ll hit spam levels of posts soon, but it would at least guide the community in some regard.
Shout out to the pride icon as well!!
