Q: Does this use the API? Will it keep working after July 1st?
A: Nope, it uses a combination of the public feed and scraping old.reddit.com. So, as long as those are still available, it will continue working. And even if they close those sources, there will probably be new ways to achieve the same effect. “Content, eh, finds a way.”
