Sorry guys, I hate to disappoint you but it is not bad luck at all and you missed the reason why! Most of the hubs there are made by novice, they publish as soon as they write something. In the past few weeks I used the Hub Hopping feature a lot and placed a few comments around, when I go back to those Hubs later most of them were longer, i.e. finished.
But one thing I agree with you, there is plenty of spam, I even found Hubs that have only a title, not even a short paragraph. But those hubs aren't there for long as someone flags them and editors remove them, thankfully.
A great issue I came across since I started Hopping is that there are plenty of spun articles on HubPages that simply are too bad to even be considered as spam, they are pure trash.
