If all Chans and alt-right forums get shut down by the (((US Gov't)))

>Those forums already exist
But nobody uses them because there are popular alternatives on the clear web. I used some blockchain imageboard once and that was petty fast. Tor sites are slow, but there are a lot of actively used forums which are based on bloated forum software. If you go full minimalism, you can make an imageboard that is usable enough if no better alternatives exist.

Remember when you felt truly anonymous on the web?

When you could use software and websites without "please type in your personal GPS identifier number ahem, I mean phone number to use our service"
