Google Adwords Landing Page Policy

I'm a newbie to IM and to the forum. Hello to all here - a fantastic forum with lots of useful discussions!

I've just set up my first site (my blog URL is in the signature below and landing page is the domain root) and my intention is to build an opt-in list then promote affiliate products to my list, and on my blog.

Thought I'd try Google Adwords as a means of building my list and refining my keywords. I'm directing my ads to a squeeze page at my domain root, where I'm offering a free gift as an incentive for visitors to sign up. On Day 1, I got clicks and these converted to opt-ins to my list, and gave me good feedback on my keywords. However, on Day 2 of my campaign, Google have e-mailed to let me know that

'We have reviewed your account and found that one or more of your sites is in violation of our Landing Page and Site Policies.'

So they have 'disabled' my site. Having checked their policies, the only potential problem I can find is under the heading 'Information Harvesting', where they say:

Examples of prohibited websites:

• Websites that offer a free gift in exchange for personal information
• Websites that request personal information to get the results of a survey or quiz

Examples of acceptable websites:

• Websites that request personal information for legitimate lead generation or business purposes

Is there any way I can keep Google happy but also give an incentive to my site visitors to sign up for my list? Would it help if I direct the ads to my blog (site/wp) instead of the squeeze page, although this may cause a different problem as I have put links and ads on the blog?
