Go to the search tab on Damus. In the top right there’s a filter where you can pick which relays you see posts from. For me half of them were unchecked. The unchecked ones were mostly spam and crap, but it just shows that (1) the Damus developers could choose to censor or promote whatever the fuck they like to their users and (2) relays by definition can promote crap or censor crap. Who knows what that could be used for in the future…
