You know, I actually asked Sweetfunny a question kinda related to this shortly after the cloud blacklist was rolled out and she made some great points.
I think it would be a serious mistake to assume that just because one blog mod complained about one comment (or 100 of the same comment made on one blog, or 100 hyperlinks jammed into one comment like that horrific train wreck above), that they should "automatically" be added to the cloud blacklist.
I mean seriously, some of us aren't even trying - we just act like we can harvest URL's, NOT remove duplicate URL's (seriously - think about it - why? - you're going to post multiple comments on the same blog entry....in a matter of a few minutes), then use the default names, emails, and comments, and just click Start Posting and woohoo we'll have the perfect blast.
If someone is mad enough to whois your name and actually call you, you ain't doing something right....I've spent some time refining my comment sprees, and learning from both mistakes and failures, and now I get more "thank you" response emails from blog mods than hate mail.
peace,
gregs.
