Ah, yes! That’ll explain it.

I use Ivory on iOS and it puts the hashtag above the post so I know it’s a post from a hashtag I follow! Quite a helpful feature.

The Home feed (in comparison to Local or Federated feeds) should only show the accounts you follow, but those posts will be made up of original posts by those you follow and anything they boost (as well as responses to and from mutual people you follow). As someone else has commented, you can hide boosts of those you follow by going into their individual profile page and choosing to hide their boosts.

You shouldn’t be getting anything else on your Home feed.
