We did this to avoid being compared to reddit and to avoid possibly having the domain seized for infringing on their IP if we continue to grow in size. I don't trust any registrar to not cave into a corporation's threats.
We're also in the process of transferring the old domain raddit.me to our new (non-US) registrar. That domain will continue to redirect to the new site. We've also acquired radd.it, which will also redirect here.
The old registrar Enom sent me a legal notice because of a post here that broke US law, and it didn't sit well with me since registrars have no legal responsibility to police content. I never willingly registered with Enom - they bought out the registrar the domain was originally registered with and we were stuck with them. Now both our server and our domain are located outside the US, along with us admins.
Reddit is closed source, bloated, filled with reactionaries, owned by millionaires and has a dead warrant canary. This site has already surpassed that privacy nightmare in nearly every way, and it will continue to be a shining example of a community-run space that doesn't treat its users as IP and doesn't give a platform to fascism.
We almost went to raddi.sh as one of you suggested, but there were hurdles that made it impractical, including the high annual cost and the fact that .sh is owned by the UK; a nation we want nothing to do with.
