Technogen is a user on mastodon.social. You can follow them or interact with them if you have an account anywhere in the fediverse.
If you don't, you can sign up here.
One thing I don't get: Can you claim your identity across all Mastodon servers? Or can someone just claim my user name on a different server?
@stanschroeder currently it seems per server, which really sucks, they are looking into some unified stuff because of it.
