havenrut43 I think there is a fundamental point that you are missing. Once you understand this idea it will put your mind at rest a bit. The key part you are not getting is that Google doesn't care about your money. They have enough money to execute their business plan. Their goal is to organize the world's information. Financial considerations are secondary to that primary goal. Their business apps like adwords and Gmail flow on from that primary goal of organisation. This means they won't show your ad for love or money if their quality score bot doesn't deem it to be "relevant" to what a searcher is looking for. They don't get care that they are flushing millions down the drain when their bot blocks thousands of advertisers.
Now that would all be fine if the bot was perfect but it's not. The bot mostly gets it right but just as often screws up. Particularly after the most recent update the bot is more aggressive now than at any time since it was introduced. If it was a junk yard dog before it's now a Tiger.
I think the way forward for you is to try to get feedback directly from the QS team about your specific case. Be polite but persistent and eventually they will help you. Don't take no for an answer. Other than that try to build a site that doesn't fit the profile of sites with low quality score. These kinds of sites are well documented on their help pages - thin affiliate, get rich quick, endless sales letters etc. Always use plenty of orginal content and make your site a substantial site - an authority site in its niche. Be persistent and don't give in. Hope this helps.
