You can still auto-post to Pages, but I suspect that will eventually come to an end too if Facebook is serious about eliminating bots.
“Facebook is sunsetting its API which allows users to automatically post updates to their “Profile Page” or News Feed. Only the Facebook API allowing automatic posts to Facebook Pages, will remain.”
The best way to protect against bots is to completely disable any auto-posting, but Facebook and Twitter can’t really do that just yet. It would kill an entire industry setup by marketers and publishers that attempts to publicize content and brands using social media. Making everyone manually post updates would become far too much work, and time spent for the return. The ROI of being on social media would diminish immensely and the platforms would diminish with it. Tools like Hootsuite and Buffer would cease to exist.
I don’t think that’s where we want to end up, but there won’t be any bots there either, so I guess we’ll have accomplished that goal. 😉
