Having read the definition of a spam blog, I fail quite to see how my blog can fall into this category.and
My blog is not spam! It is nowhere near spam!!all reports, such as these, are coming from people who don't know about fuzzy logic.
You spend a lot of time publishing, and publicising, your blog. You want a blog that's interesting, innovative, up to date, and / or useful - and you want readers who appreciate your effort.
Spammers are very innovative, and they constantly adapt their product.
The police cannot stop arresting people - for fear that they might arrest innocent people. Similarly, Blogger cannot stop classifying blogs - even given the possibility that some blogs may not be righteously classified. The general real world population deserves to live in an environment with lass criminals - and the general Internet population deserves to surf in an environment with less spam content.
The typical spammer doesn't worry about content that's interesting, innovative, up to date, and / or useful, he just wants content that looks like it's legitimate. All that the spammer has to do is find your blog, scrape the content and put it into his blog, and then add the spam to his blog. Voila! A splog that looks legitimate!!
To keep up with the ever changing splog tactics, Blogger has to constantly adapt their abusive blog detection process. Blogger finds a typical malware / porn / spam host, extracts the content - which may include content stolen from your blog - and adds the content to their database. Then they look for more blogs like the one just detected.
Along with finding other blogs from the spammer, they are going to find your blog. And they will label your blog as a suspected abusive host - and there is another false positive.
Some splogs won't be detected by Blogger. If the splogger just scraped content from a new blog, with totally different content or style, Blogger may not notice the spam inside the content. They will overlook new content - and there is another false negative.
The more Blogger reduces false negatives, the more they will increase false positives. That's without any additional effort from the spammers.
If the successful fuzzy detection interferes with the spammers bank accounts, the spammers simply activate more botted computers, re double their publishing activity, and there will be more splogs - and more false negatives - for a while. The spammers like their jobs, and their paychecks. You don't want them to take a cut in pay, do you?
The fuzzy detection process, plus ever increasing spammer activity, ensures that there will always be more false negatives and false positives. The "My blog is not spam" forum reports won't be going away, within this lifetime.
