Hi Bob,
Yes, I have seen this and expect many that are not making much money or very little to shut their sites down soon. The newbies might as well shut down for they have not a prayer making it in this business. For the rest of us only time will tell. I will say this many of us are now at the total mercy of Google and other major search engines. It is a very volital situation we are all in. If I am contacted by the US Gov. and told to shut my sites down, I will comply asap. This is a possibilty that we, that have good search engine ranking may face. Those at the top will probally be contacted first and so on. It stands to reason if the major search engines are bailing out of online gambling advertising, then they know the deal. They have obviously been warned to discontinue or face legal action. Are our days number in this business? In my opinion I think so. How long do we US webmasters have left? Only time will tell.
