Well, it varies. Some platforms are very lenient when it comes to reposting a story on your own story. They see it as a form of sharing and spreading content, which can be beneficial for both the original creator (in terms of more exposure) and the person reposting (in terms of having interesting content). But, there are also platforms that are strict about copyright and ownership. If you do it without permission on such platforms, you could face consequences like having your post removed or even getting your account in trouble. So, the short answer is it depends on the platform and the circumstances.
