Oh, cool! So, yes, I'd highly recommend the book I wrote for O'Reilly Media about ActivityPub:
@kleisli @MichalBryxi great. I can't do that for you. You can make a feature request to Mastodon to hide notifications from particular servers, or you can block tags.pub or add hashtag NoTagsPub to your bio.
@kleisli @MichalBryxi Mastodon has that!

@MichalBryxi @alex @smallcircles it's a hack, agreed.
@MichalBryxi hi! I'm one of the authors of ActivityPub and the developer of tags.pub.
There is not a native ActivityPub way to follow a hashtag.
Following a hashtag in Mastodon only shows you everything with that tag that is shared by someone on your server, or someone that someone on your server follows.
The point of tags.pub is to follow hashtags globally.
If you don't want to participate, block away!
@smallcircles @alex @MichalBryxi it's pretty common on the Fediverse.
That said, I'd love to add vocabulary terms for it. And you could edit your actor object and add them.
