Rebuild a fully-functioning Facebook import by scraping data
Facebook is still the #1 place for most people to post events. Although the official FB api is still stagnating, there are other solutions that can work just as well (in addition or in place of the current Tribe Extension).
1. Use the .ics feed. Thats what Time.ly and other competitors are doing.
2. Parse the URL. This method (used by geodirectory: https://wpgeodirectory.com/social-importer-v2-beta-released/) lets you get information thats neither in the .ics or the old API.
