Why is Threads recommending these weird spammy posts from people looking for 'friends'?

Engaged readers often notice odd posts on Threads, where strangers request to be friends through selfies of young people. These posts, sometimes with "Age doesn't matter" captions, are now popping up frequently in users' recommended content as they explore the app. Examples include a Spotify post linked alongside another from an anonymous account and Meta CEO Adam Mosseri's personal post appearing multiple times. While Meta confirmed these aren't genuine recommendations, details on stopping spam remain unclear. Similar issues have been reported elsewhere on Meta platforms like Instagram, with users facing persistent推荐 of similar posts that can be reported but continue to surface.
