On Bing pull this query:
for me Yields 363,000 results..
Now here is the trivia question: how many of those pages are not a part of Link/Content Spamming, Auto Generated Garbage, Scraped Content, Comment Spamming ... etc.?
Now using Bing again try:
site:Blogetery.com +'insert your favorite spam-term-here'
And that would Represent whole bunch of blogs of Real Bloggers that do not know how to delete/control comment spamming.
I feel really bad for the legit users of a free blog platform, but in theory numbers speak for themselves here.
