Interesting thread over at Threadwatch - Lockergnome & Co Scraping Wikipedia for Profit - Wrong? Mixed responses, some think it's ok making money out of other's efforts by doing this some don't. Don't forget, they aren't scraping the SERPs or similar here, they are scraping Wiki's that people have put a lot of effort into. Something I also noticed: Both hosted on the same IP and also: http://www.smartpedia.com http://www.quotesplace.com Two other Wiki clones by the Joel guy who makes $25k per month using adsense
Wikipedia allow republishing of content for commercial means - it's quite clear to anyone who writes content for Wiki that this may happen to their work.
