Publish it offline as well, put it in your local anarchist zine, print posters.
Things to do with the location of camps near you:
Spread that specific information in your area.
Get people together. Talk about this. Consider what you can do to spread more information and get more people together. Maybe distribute information at crowded local places.
When you have a good lot of people, hold some solidarity rallies outside the camps. Inform yourself about your rights before hand. Don’t get yourself all arrested if this is your first step into action and you don’t know each other well.
If you have a good reliable group of people together and have done some minor actions, start first talking about and then training for more direct actions. Learn your legal rights. Invite activists who can help you as a medic, legal team, etc.
When you’re ready, blockade the traffic going in and out of these camps.
Consider moving to more disruptive actions from there.
