You only joined 6 days ago so you need to get some perspective here. Followers, money etc come over time and there are a lot of steps to hubbing successfully. I would read the learning materials here all the way through. Search for hubs on how to best monetize and gain followers. If you've only been here for less than a week you can't expect to see money and tons of followers rolling in yet.
Writing hubs takes TIME and a lot of patience and persistence. The longer your hubs are published the more traffic you will get and followers as well.
As for "unfollow" - it has a purpose. Say you are following a hub and it's getting hundreds of comments. You don't want to get email alerts after awhile so you can click the "stop following this hub" link in your email.
You also have the ability to not follow other hubbers anymore. Say a particular hubber does something offensive and you were following them - you have the ability to not follow them anymore which is a good thing.
People who scream that HubPages is a scam are the ones who, in my mind, didn't try hard enough or wanted easy money for no work or effort. That isn't how it works.
Keep working at it and keep learning the system here. There are plenty of us who use HubPages successfully and you can too if you are patient with it.
