For my "custom search engine"
I blacklisted a website called "globalspec". To me it is a most annoying website, a morass of useless, keyword rich pages that seem to come up in response to every query. That they are useless is not immediately obvious, but they are. The result is a lot of wasted time.
I would like to know if your opinion about globalspec is different.
Right now I am up to 55 sites blacklisted and parts searches are much more useful.
I am not excluding ebay for now, I figure that if you do not want to include ebay, you can always say -ebay in your query.
I did searches for a few part numbers that Spehro mentioned, and, to my delight, the worthless spammers were not seen in the first 3-4 pages.
