Well, if you must ask...
nulled.red is a moderated Mastodon instance made by me, Mike Cole. Hosted in Roubaix, France. We also don't block or silence any instances. Get a full view of the fediverse!
If you want to help keep nulled.red and my other projects up and running, feel free to donate with Liberapay. You don't have to do this, but It'll help out a lot.
Mastodon is a social network based on open web protocols and free, open-source software. It is decentralized like e-mail.
