Râu Cao is a user on kosmos.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.
PSA: if a user habitually boosts stuff you don't want to see, you can turn off boosts just for them without unfollowing them
view their profile in the regular masto UI and you'll see a "Hide boosts from X" in the hamburger menu
this can make the whole experience a lot less annoying, but it's not well-known!
@technomancy What Mastodon version is that? It's not in the latest stable release. Could be that your instance is running a fork?
