Unfortunately Squidoo have changed their policies regarding lens subjects. You may have seen this last month. The policy came in to force on the 16th July and they have now begun locking lenses that break the new policy.
You can see the list of now unacceptable subjects here: SquidDon't!
Basically lenses on the following subjects are not longer allowed: pharmaceutical, drug, diet aids, weight loss, dieting, ebooks and affiliate programs for medical cures, dating, affiliate marketing, gambling, credit cards, mortgages, forex, finance, hate lenses, ringtones, adult, traffic exchange, PTC, advertising, plus more.
