Adware web sites can't be expected to be similar in quality. What can be done then? Start by attempting to locate the top adware web sites which *will* exist somewhere. When you arrive at a page which looks autogenerated or it looks neglected, you can go elsewhere.
When you are trying to find adware online more web sites can be found in web guides with static links in which quality sites only are included. Some time back such directory pages were well-known but they are out of favor as direct search tools have got better.
When searching for adware using a web search engine the resource that's just what you need could be very new. Using an engine with advanced search by date if looking for adware will let you locate the most recent results that engine can find. Some of the best search engines also let you find related or similar web sites which shows more adware related web and web 2 sites which you can then click on.
