Thank you all for your responses!
As I anticipated, it appears there is no organization solely focused on this issue, which is concerning. Attaining pseudonymity or anonymity online is a multi-faceted effort, therefore safeguarding it necessitates addressing multi-faceted threats, which can’t be done in fractions.
For instance, TheDoc has mentioned the Tor Project:
Sure, the Tor Project aims to create a reasonably anonymous network on top of the TCP/IP stack, and they made significant progress toward that goal. However, relying solely on Tor is not enough to protect against threats to anonymity. What is the point of concealing your network activity if the website you visit requires age verification? In fact, Tor explicitly addresses this issue in the Tor manual:
If you visit a website using Tor Browser, they don’t know who you are or your true location. Unfortunately many sites ask for more personal information than they need through web forms. If you sign in to that website, they still don’t know your location but they know who you are. Further, if you provide: name, email, address, phone number, or any other personal information, you are no longer anonymous to that website. The best defense is to be vigilant and extremely cautious when filling out web forms.
Anonymous95 has mentioned various activist groups and private communication companies like Signal, but this brings us back to the original point: these organizations are not primarily focused on anonymity. While they may rely on it (like the activist groups) and offer some support, their main purpose is not to defend it. Moreover, it appears that they are not making significant progress toward that goal.
In contrast, some groups are actively opposing age verification checks, which inadvertently helps defend anonymity, even if that is not their primary intention.
For example, one group that hasn’t been mentioned is the Free Speech Coalition, which advocates for the interests of the porn industry. They have been actively engaged in legal battles against age verification bills in the United States. They provide a range of resources for this effort, like a bill tracker (Age Verification Bills – Action Center), a map of state AV laws (State Age Verification Laws – Action Center), a global policy tracker (Global Age-Verification Policies – Action Center), and website modals that you can integrate in your platform that inform viewers about the issue (Advocacy Tools for Websites – Action Center). Despite not being primarily focused on anonymity, they are arguably one of the most active groups opposing these laws in the U.S.
So as I see it, as of 2025, online anonymity advocacy is fragmented across numerous organizations, each supporting anonymity in various ways and to differing degrees. This is really bad. If we have a chance to effectively combat these laws, I believe we need a dedicated organization focused solely on this issue.
