Well, it really varies. Some platforms allow you to repost a reposted story without any restrictions. But others may have limitations, like if the original source has set certain privacy or sharing settings. For example, on Instagram, if a user's story has been reposted by someone else and you want to repost it again, you need to make sure it doesn't violate any copyright or privacy policies. If the original story was set to be publicly shareable, then generally you can repost it again. But if there are restrictions on the number of times it can be shared or who can share it, then you might not be able to.
It's not usually allowed. Even if a story has been reposted before, you still need the original creator's consent or a license to repost it to avoid potential legal consequences.
Yes, on some social media platforms you can mute a reposted story. For example, on Instagram, if the original story allows for muting, the reposted version might inherit that option. Usually, there's an option in the settings related to the story (either the original or the reposted one) to mute it. This can be useful if you don't want to see the story repeatedly or if it contains content that you're not interested in.
There could be various reasons. It might be exclusive content or have specific usage terms that prohibit reposting. Sometimes, the owner simply doesn't want it shared elsewhere.
