Bearshare links?

[EcommerceSite]

I am doing competitor link research and so far 4 of the 4 have had links from search.bearshare.net What kind of site is this? I am sure it isn't valuable but I can't figure out how it is getting crawled.

Do you have sample URLs where the links are coming from? The site looks like a search site, and it's possible that the search results are being indexed by Google.
