Is it worse to write relevant content on your own blog and post it, or to troll the rss feeds and jump on content that someone else wrote and post it all the time? The latter one seems even more fishy to me. If you create bad/irrelevant content wouldn't the constant down votes solve the problem?
There are several people here who I would gladly mark most of their posts as spam because they submit each and every thing they write on their blogs.
How about an adsense like blog spam sidebar where the crappy submissions have to sit in shame?
I tend to agree, but my point is: Spam is spam and good posts are good posts, your own or otherwise. We shouldn't define "good form" based on how we want the morons to behave.
