I think the idea is good, but for the issue that no one but pedophiles use Tor.
Despite the kike-loving developers, It's a place with a huge potential for the dissident right of we actually began using it, it's a place we can use to organize, and get our shit together, with much less fear of our government.
Like i said, anyone could remove any post or thread they don't like, if enough pro-whites used the site from the outset in order to immediately delete the pedos and make up the majority of the site's content, all the issues we face will not cause the site to become overabundant with CP-posters and die as a result, the trick is to somehow figure out a way to get the people who we want onto the site in large enough numbers to prevent the cancer from growing.
I think another issue is that we insist on national socialism as part of our vetting requirements, I, for one, don't exactly now what set of policies you refer to as "national socialist" and a lot of other potential recruits do not know as well, those who become advocates of the white people are not the type to sign up to an ideology they do not fully know of (and since the natsoc of the modern day is not a 1:1 with the natsoc of 1940's germany, they cannot simply read mein kampf to find out).
nonetheless, they are steadfastly in favor of the white race and it's prosperity, they know at least some of the issues that face this people and do think they need to be addressed.
I bring this up because perhaps we are too selective about who we can call "brother", right now we need anyone who unironically fights for the interests of the white gentiles and their children.
No matter what political ideology they may otherwise subscribe to, the twin traits of only taking natsocs and unwilling to describe in detail what set of policies a natsoc society has, is going to ensure a permanently dwindling number of recruits.
Either you can think about what's essential in an ally and go for that (essential meaning to ask yourself "what is the one issue or trait that is most important here?" and only recruiting on that basis, recognizing that you are, indeed, desperate for whatever allies you can get for your cause right now), or actually explain the full extent of what it means to be natsoc (the full consequences of natsoc gaining power over a country) before asking people to sign up to it, or you can do both.
Also, get /pol/cks and /pol/-types to start using Tor, despite the shittiness of the devs, get them to realize it;'s a good tool for circumventing the LEA and other alphabet soups and communicating with fellow dissidents.
The image board idea is not the issue, the issue is pro-white online community in general, it prevents us from making the numbers of active people we need to make this imageboard work.
Blaming the imageboard idea is a deflection from the true underlying problems our movement is facing that cause such a plan to be destined to failure.
At the very lesast, we need to get our asses on Tor and make some onion site that caters to our type of mindset, (or specific subtype if you still feel that total conformity, exclusivity, and high standards is still the way to go).
