The problem is also around people artificially liking and commenting on your own posts (if they are public). I had encountered this last year when I was running a photography project and I would have to deal with fake accounts posting on every image. Each would post one of the following messages: 'Nice! Check out my page!', 'Wow! Cool pic. Want to increase your followers, click the link in my profile.", "Very nice. Follow back".

I don't want that spam in my image comments (considering there would only be 1 or 2 comments from real people and 10+ of these). I had to go through and manually delete them, block the users (achieving nothing because there are so many of these spammers).

This is a serious UX problem that has turned me away from Instagram (which was the "best social media" platform before they destroyed the chronologic timeline). I don't care if people are using an API to post legitimate content (I would have loved the ability to post content to multiple sites at once (twitter, IG, ...)). I care when the API enables annoying spammers.

This is not so much a ux problem as an "marketeers gonna marketeer" problem. It happened before with blog comments, it happens now with "social" media, it'll happen with whatever comes next. If it's remotely exploitable for personal gain, there's going to be people exploiting it.
