Ask HN: How do you comply with GDPR when scraping from third-party

I've been tooling with the idea for a project that relies heavily from scraping player data from a game. I of course want to comply with GDPR but I'm wondering how to do so. Would I save who had their data deleted in the database, and then purposefully ignore those when updating the database? I assume you aren't allowed to keep re-scraping someone who requested their data deleted.
