Feature request: following to separate users, not to Hubs

Feature request:
Make following to separate users, not to Hubs.
One user - one merger site.
So user will be able to decide what to read and support.
This will solve problems with spam and unwanted content.
When user follows another user, he also downloads content of users who this user follows (friends of friends).

```
user1 --> user2 --> user3 --> user5
\---> user4

```

user1 has user2 in following list. Also user1 has user2, user3, user4 merger sites. And does not have user5 merger site.

Interface will have 2 lists of posts:
- following: content of following users (user1 see user2)
- network: content of following you following (friends of friends) (user1 see also user3-4)

Than user can see content of other interesting users and subscribe to them(for example user3). After that he starts download content of users who this new user follows (user5).
If user sees something unwanted he can block this user and don't download he's followings.
So user can build his own social network of interesting users, and minimize the appearance of spam and unwanted content.
