I know a lot of people are angry about the idling policy, but I don't think you should be.
Hubs get idled because they receive virtually no search engine traffic. Idled hubs simply get de-indexed to remove them from the search engine index. If you have another traffic source (i.e. Pinterest or another referring website) you can still send people to the hub and earn money from the views and the ads.
If an article goes two to three months with no search engine visits, then HubPages is doing you a favor by idling it. They're telling you that, as is, this article is worthless. Hate to say it, and people hate to hear it, (and I'll admit I've published plenty of worthless pieces over the years) but it's the truth if you want to approach publishing as a business.
For some articles, there is no hope. There's simply too little search traffic or too much competition. For others, you can tweak things like titles, subheadings, and word choice to appeal to slightly different keywords. This is one advantage of writing long hubs (1,000+ words). You're more likely to use what are called "long tail keywords" in your post, and therefore rank for low competition, long search phrases.
For example, I've written about modeling comp cards before. These can be called comp cards, composite cards, zed cards, sed cards, and other similar things. Most people searching for them, however, use the term "comp cards." If I write my article using "sed cards" in the title, subheadings, and throughout the text, I'm not going to receive any traffic - even though the article may be well written, informative, and useful. Change the article to use "comp cards" instead of "sed cards" (and maybe keep one reference to the odd spelling for those people that do search for it), and suddenly I've got a much larger potential readership.
If you're publishing for vanity and not for business - i.e. you want to display a bunch of poetry, philosophy, personal ramblings, or whatever - then you should definitely move to a different venue. If you're publishing for business, you should edit the hubs you think target a reasonable market and delete the ones that are hopeless.
I get the feeling this is a somewhat unpopular opinion, but somebody's gotta point out the obvious and break up the echo chamber here in the answers/forums.
