To be honest, most of the Flickr groups seemed completely useless, full of HDR junk and asinine motivational stuff. Though I'm sure it's a bit like Reddit — the good communities are small and hidden.
Follower spam is another example of noise, and something Instagram is also rife with.
The good ones kept those gaudy things at arm's length. Some of these groups have a bit if an attitude at first, but as they get to know you and your dedication, they will warm up to you.
Social media does have tough challenges ahead, especially as bots/spam become more and more prevalent.
I would love to work on a bot-prevention team somewhere, but my background isn't in ML.
Case in point: Google visibility, if you are not Wikipedia no amount of quality content will get you above the link farms if you don't also follow the customary rites of pleasing the algorithm.
Bots can definitely contribute meaningfully in many ways. Mostly through organization (suggesting labels & other metadata, album creation, etc), spam filtering & rule enforcement (like reddit's automoderator), and even automatic editing (like some of the stuff Google Photos offers, like rotation suggestions and various automatic filters).
Since you're here, may I voice a thing I really enjoyed about Flickr? Community and actual human communication.
Perhaps in the mobile era this isn't possible anymore since everyone is attention starved and tiny screens and keyboards aren't conducive to longform communication, but this was Flickr's strength.
You'd find a group where your photos were relevant and start conversations with strangers halfway around the world. The ability for groups to self-moderate is key because it kept groups on topic. I just poked around some communities I used to frequent like Hardcore Street Photography [0] and Guess Where SF [1], and they're surprisingly still habited.
Instead of trying to be another Instagram, I hope the future of Flickr will play to its strengths.
