Nasty letter from Google. What the heck?

I received a notification from Google today that they have disabled my adwords account due to violation of their terms and poor quality of landing pages or something.

Here's the thing - I HAVEN'T ADVERTISED IN TWO YEARS and even when I did I only had one campaign going for about a month and when my budget finished so did my advertising. (And I wasn't advertising anything unethical - I promise).

Any recommendations about how to rectify this?
TIA


Here's the text of the letter:

Dear advertiser,

We are writing to let you know that your Google AdWords account has been disabled due to one or more serious violations of our advertising policies related to Landing Page and Site Quality. As a result, your ads will no longer run through the Google AdWords system and we are unable to accept advertising from you in the future. Please note that future accounts that you open will also be disabled.

As part of our commitment to making the AdWords experience safe and effective for our users and our advertisers, we routinely review the landing pages that our advertisers promote through our search and content networks. If we find that an advertiser has submitted a landing page that egregiously violates our policies, we reserve the right to take immediate account-level action.

Landing pages advertised via AdWords must have relevant, original content, and must be transparent about the nature of the business being promoted. Furthermore, advertising certain types of sites will lead to immediate account disabling. These types of sites include, but are not limited to:
• Sites that charge users or collect personal information in exchange for a product that is never delivered
• Sites that charge for "free" software
• Sites that trick users into paying for fake or poor-quality content
• Sites that charge users for information that makes unrealistic promises of financial or personal gain
• Sites that install malware software on a visitor's computer
Please note that this action is related to sites that have recently been advertised through your account. In a review of your account history, we found that your account had submitted a least one site that egregiously violated our advertising policies. Although you may have removed these sites since our latest review, advertisers that have a history of promoting these types of sites are still subject to account-level disabling.
