What makes it spam? We're invited to lemmy.ml, it shows up on our homepage the same as it does yours (probably even higher because instances more likely to downvote or ignore political posts don't link with us atm).

If you meant flooding, it's not that either. We're a big instance (1k users weekly) with a general interest in politics and a historical anti-lurking culture, so we'll be disproportionately active in political threads compared to a general instance like lemmy.ml, just like programming.dev is in tech threads. Are we meant to just not share an opinion because too many other people in the same instance already posted their (different) opinion?

You can just make your own instance where only people with brains as smooth as bowling balls are allowed and defederate with the rest of us. I guarantee you that everyone will be much happier.
