 This bot is intended to be run a short time (e.g. 10s) before Eventbrite event tickets are released (use the `ticket-info.js` script described above to find the ticket release time). Its main purpose is to secure tickets for events which are sold out very quickly.

 ## Bugs and Issues
 1. There are two types of layout for Eventbrite event pages. Both scripts only work for events whose Eventbrite page contains a big header image (see screenshots) - this is the type that you will see most often. Neither script will work for events that list tickets and prices in a table - see https://github.com/Dalimil/Eventbrite-Tools/issues/3#issuecomment-256580440.
-2. Ticket-Info script used to obtain more information about ticket quantity, but it recently stopped working. Hint: this JSON item suddenly appeared in their collection: `"json_blacklist_set": ["event_tz", "event_level_info", "quantity_sold", "quantity_remaining", "request", "quantity_total", "waitlist_settings", "taxoptions"]`. Can someone figure this out? (Also see https://github.com/Dalimil/Eventbrite-Tools/issues/4)
+2. Ticket-Info script used to obtain more information about ticket quantity. Eventbrite added this JSON to each ticket collection object and the fields are no longer accessible: `"json_blacklist_set": ["event_level_info", "quantity_sold", "quantity_remaining", "request", "quantity_total", "waitlist_settings"]`. Can someone figure this out? (Also see our partial workaround: https://github.com/Dalimil/Eventbrite-Tools/issues/4)
