Today I received the following email from Amazon:

Dear Publisher,

We noticed your blog (listed below) has not updated for more than 60 days. Kindle customers expect to receive frequent updates for blogs and news feeds to which they subscribe. Because blogs should update at least once per month, we are cancelling blogs that have not updated in more than 60 days. Accordingly, if you do not publish new updates within 7 days, we will remove your publication from the Kindle Store.

Blog Title: MobKool | Blog ASIN: B002IKLLRG

Sincerely,
Amazon Kindle Team

Of course, by publishing their email, i dodge the bullet.
