Lots of people in this thread are claiming that it doesn't based on gut feeling, but consider:
- Facebook publicly claims it does [1]
- Mark Zuckerberg testified in-front of congress and stated they do [2]
- Multiple government regulators have specifically checked that it does in their privacy audits. [3]
They might be lying and actively conspiring to not delete it, but they'd have to have a very good reason to take on that much legal risk.
Now, consider:
- A infinitesimal fraction of facebook users try to delete anything.
- Facebook makes money from your data by showing you ads. If you stop using facebook, you stop generating any revenue and your data becomes a liability, not an asset.
What reason would there be to lie about it?
