Social networks have restrictions on commenting functionality to prevent spam and abuse. Here’s what you need to know:
  1. You can only comment on posts that belong to your own social media accounts/pages. These can be posts you or others published on your account/page.
  2. You cannot comment on posts from on users’ accounts or pages. Again, the social networks have this restriction to prevent spam and abuse.
  3. This is a limitation enforced by the social networks themselves (especially Meta platforms like Facebook and Instagram) through their official APIs.
  4. Even if you try to cross-post a comment, e.g. on Instagram, it will only appear under your own posts, not other users’ posts.
These restrictions are security measures implemented by social networks to prevent automated spam commenting through APIs. Please see the Comments API documentation for more information on how to comment on a post.
