Glad to see this post going around - more eyes on the issue is always better. If you are hearing about this for the first time - welcome to the party. We've got a lot to do and more hands are always welcome.
Adding to this with some great resources provided by others in the replies - I encourage anyone who wants to get organized to hunt through the replies, this post has gone big and I am for sure going to miss things.
Real quick though - I see a common theme repeating of "It's too late for this" / "There's no stopping this." I think about public writing as rhetoric - about language as having a purpose and an impact.
I will tell you this as kindly as I can: Make your own post.
Venting is fine. Framing cynicism as "honest" or "realistic" is ideologically disingenuous and actively undermines every effort to organize. Every time you work for change and work to organize a movement, you must be an optimist, especially when it comes to the impact of many dedicated and motivated people.
We can do this. We will. Here's more on how:
For Tumblr - there is one specific thing that can be achieved by feedback to tumblr/auttomatic - get them to change the service doing verification. Tell them that 5CA has a track record of incompetence in this exact realm. At the very least, a different company might treat your data more carefully until these laws are taken off the books.
US based with international resources - Electronic Frontier Foundation
For the USians - NetChoice.
Specific Links By Nation - from the notes:
In Australia - this is the link to the legislation people are pointing at. Since this has already passed, it will be a tough road to hoe for our friends down under for sure - but hey look at Hungary, maybe 'tis the season for getting governments in line.
In Brazil it appears there is an open forum for citizens to show approval or opposition to a law - my Portuguese is impressionist at best but this link was provided by one user
In Canada S-209 appears to be the relevant legislation to oppose here, get in touch with your MP.
In Germany it looks like the best action to take is going to be at the state level - this article about social media age protection might be a good starting point, but I have not yet seen a link for an organizing group (and my German is limited to ontological terms).
Finally - Tumblr is not where activism happens. Engaging with this post is not step 1; this is step 0. If you want to get involved - go search "Chat Control" / "Age Verification" / "Social Media Ban" in your state and country. Find the people who oppose them and get behind that movement.
Local resistance has a massive force multiplier; the more specific your advocacy group is, the bigger the impact you can have. And you can have an impact. We all can.
Good luck, have fun, let's change the world.
