As of just now, I've removed facebook as a login mechanism for joining or signing in to Boxscore Geeks. This isn't really a #DeleteFacebook moment. We still have a facebook page, and still integrate with facebook in a few ways. In the end, what it came down to is that Facebook was making it a pain in the ass for me to maintain this functionality with constant changes to their API, frequent deprecations that made me edit or upgrade code, and other ridiculousness, so I looked over at the twitter authentication that has functioned entirely unchanged for five years, and thought, "ok, screw this," and just removed this feature (which I now believe has been broken for a few weeks anyway).
If this affects you, I'm really sorry. If you've connected to twitter as well as facebook, you can still log in that way. Otherwise, you should be able to send yourself a password reset to be able to log in that way. If you encounter errors with each of these, feel free to use the contact form to let me know about it.
