YaCy, being a distributed search engine gets results from many sources. Since you cant trust anyone it crawls each result looking for the keywords (if I remembered correctly) Thus, we can have multiple search providers (and multiple gui's) Subscription based ones with free indexing, free ones with subscription based indexing, ones with a subscription for results and for indexing and ones with free indexing and results for free. Providers can still insert spam into their result but it will have to be marked as advertisement and will quite appropriately be moved to the spam tab or removed entirely.
