Get off discord. The SPLC and ADL have access to everything due to the discord admins being furry communists. IRC and rocketchat will be good alternatives although I am skeptical of rocketchat's performance.

Don't rush in and add user created subreddits right away. Allow the culture to foment a bit to avoid hostile elements repeating a voat. I was a coontown founding moderator and tried to work with Atko on limiting our userbase from taking over the site, he didn't listen to me and now voat is shit.

Figure out a good balance between free speech and crudity. I doubt you guys want to allow racism like one could find on /r/coontown, but at the same time civil conversations of race should be allowed (which was not the case on the_donald previously).

Might want to start networking with professional trolls, though I know this will fall on deaf ears.

The best way to maintain a website is to have fresh content daily. I suggest adding a "catch" to the site to promote traffic, perhaps restart AMAs and such.
