I’ll admit that I have spammed blogs (and still do, when I’m extremely bored or fustrated with current rankings. Usually after 2 minutes I get bored and stop so no comments please.). I see this as a game and the person at the top wins. Every game has fair players and cheaters. When the cheaters are caught out the fair players are satisfied temporarily. The cheaters simply find a newer and more efficient way of cheating. Many play a combination of both.
Fact is, It’s irrelevant weather or not a site is spammed to the top or not. On topic spam is still on topic.
Blog owners. If you don’t like spam, then do something about it! As f&p said:
If they don’t wish to have tons of links for viagra, online casino, car loans etc. it is within their power to do something about it. The blogs where I see this is where the owner hasn’t been around in a long time. Any popular blog with lots of current traffic doesn’t seem to have this problem
One last thing. Submitting reports to Google and Yahoo won’t help. This is not a new tactic. ALL search engines know of this and I would be willing to bet they are searching for new ways to filter this out.
