Why was I seeing what I can only call advertisement-posts on beige.party, but not on kolektiva.social?
I wasn't following those accounts. The posts weren't boosted at all, as far as I could tell - and certainly not by anyone I follow.
So...can an instance just shove posts into your feed? I thought that your feed is just the posts made or boosted by people you've chosen to follow, right? Mastodon has no algorithms. Does it?
Not a big problem. I blocked the two advertiser accounts as soon as I became aware of them. But it's odd, and that makes me want to know why it happened.
