As you can see in this example, shared by app researcher Hammod Oh, Instagram's testing a new 'Public' folder in your DM inbox which, as the description explains, would enable you to:
|"Message or share your favorite posts directly with your followers."|
Back when LinkedIn initially launched its long-form publishing platform, for example, spammers loved it because every time you saved a new post, all of your LinkedIn followers would get a specific notification in the app, providing a quick and easy way to reach a lot of people, free of charge. Spammers caught onto this, and within a couple of months, LinkedIn had to limit the prevalence of such notifications to stop people misusing it as a blast option.
Can imagine the same happening on IG? That could make those message notifications get real old, real fast. I assume Meta has a solution in mind for this, which would restrict potential misuse - but then again, as it desperately looks for anything to keep people active in the app, it wouldn't be surprising to see them roll it out, then deal with the consequences.
Over time, as more and more social media users have moved away from public posting - and the scrutiny that can come with such - they've increasingly become more reliant on private groups and DMs to share content with friends, with the News Feed becoming more of a discovery surface than an engagement platform within itself.
Meta's top executives have reiterated this - earlier this month, Meta CEO Mark Zuckerberg explained that:
|"Most people use feeds to discover content and use messaging for deeper connections."|
