You ignore it. You can thank them. But mostly of the time its just something people do. Its like getting a like on facebook.
Following means watchlist so they can see your latest post, comment etc. Buyers use it to keep track of artists.
Features are on groups. You don't have to create your own group if the only thing you want to do is feature people. Its a lot of work to own a group, like owning a pet.
Fav's etc help a little bit in the search but mostly its a time waste, you can do the same for them but you would be better off advertising their work, or your own.
