A snap belongs to the person that created it. No moderator or chief can ever completely delete someone's snap, but they can remove it from their tribe. Only the original creator (or in certain cases, a Snapzu admin) can completely remove it. Snaps can be submitted into up to 5 different tribes. Snaps generally require a bit more information when being submitted, such as title, introduction (optional), cover image (optional) and snap type, and it's purpose is mainly to share links, images, and videos with the community.
A text post is designed to be simple to make and is mainly used for creating discussions within a single tribe. It belongs to the tribe that it was submitted to, and can be moderated by the chief and/or moderator(s) of said tribe.
