This is not normal. I would take a look at how you are trying to monetize your hubs.
Are you utilizing adsense? If you are, then maybe broaden your horizons a bit and cover some up to date subjects. Things that are in the news. Yes, hubpages likes evergreen subjects, but the competition in making money articles is fierce, and you are limiting your audience.
Change your avatar to something people will remember. Whether it is a picture of you, or your cat or something else, There are 1000's of other people using the stock avatar, and some of those are spammers.
Some readers look for customisation as a sign that someone cares about their reputation here.
If you can get an Amazon acct, put some related amazon products in your articles. They don't make a ton of money, but sales every few days can add up to a nice sum eventually.
In just taking a quick browse thru your hubs, I see that you don't seem to use images or videos in your hubs.
While they are not a requirement, they can bring a reader to your hubs, or at least hold them for a few seconds. Perhaps they will see a link they like or so on.
Why do all the hubs you produce have quotes in the title? How about writing a couple without and see if that gets you more traffic.
For some reason, on some of your hubs, the google ads are not targeted at all. I don't know if there is some issue with crawling your content or what.
An article on Starting your Owm business offers ads for play games online, while others do offer targeted ads. Maybe the hub is too new.
If you want to experiment with a different style, open a new account, copy your aff setting over, and try a different style and see if you have better results.
Hope this helps you. I am half asleep, and not really in writing mode yet.
