Privacy of the shared contents
Once something is uploaded to the Internet, it is likely that the uploaded contents can never be deleted because
- it’s not always possible to delete the uploaded resources in the server; and
- there’s no absoulutely legitamate way to delete the backups of the uploaded resources at other locations where you have no access rights, for example, others’ computers.
In short, there’s no absoulute privacy for contents uploaded to the Internet. They’re expected to (be exposed to the) public.1
