Short-lived posts only kept alive by boosts and reposts. Otherwise the post will disappear.
Paperplane is a simple, fun and a realtime community where posts are kept alive by engagement from followers.
Each post is short-lived as long as the followers finds the post relevant or irrelevant, meaning you cant have a post from years ago still be visible to the public or on your name - unless that post from years ago is of course still being boosted and reposted... :)
Happy paperplaning!
