We created a mobilizon instance to experiment. It can be used by anyone, but you should expect a lot of chaos there.

Check out the instance at:

mobilizon.libr.events

Note, librevent is not intended to be an automated scraping system but a scraping system that is used manually. This instance is also used to test mobilizon-poster, so you may notice the presence of artificially created events. Here the Instance configuration.
