Editing Retroactive policy enforcement (section)

====Data harvesting====
Retroactive amendments to privacy policies often permit the collection and processing of consumer data in ways that were not authorized at the time of the initial agreement. Once the data is shared or used, the damage is often irreversible. For example:

*'''Example 1:''' A social media platform updates its privacy policy to allow third-party advertisers to access user-uploaded photos and personal data. By the time users become aware of the change, their photos and data have already been shared widely, with no option to retract or delete the information.
*'''Example 2:''' A smart home device company retroactively introduces a policy allowing audio recordings to be used for training artificial intelligence systems. Consumers who relied on the company’s earlier assurances of privacy have no way to undo the sharing of their sensitive recordings.
