I'm very doubtful they voluntarily delete your data.

I believe they always retain all data forever, as a trade secret. They don't need no stinking laws to do that.
This is a component of not requiring users to pay for premium service. When you "create an account" you're simply "activating/linking/merging" one of your shadow profiles to your IRL identity (or not-so-IRL personas), which (possibly) has always existed (long before you showed up), claiming it as yours, and publicly exposing whatever Facebook is willing to show you that they know about you/that persona/whoever.
If they stick to those habits with European users post May 25, GDPR will mess them up pretty bad. It would require just one whistle blower to expose their wrongdoings.
GDPR?
Facebook needs to clarify what actually happens to data.
