Spam Classification And Review Accuracy Improves

At any given time, we can see a small sample of the Blogger blog universe, as reported in Blogger Help Forum: Get Help with an Issue.

One sample, that we may see, is composed of the blogs which have been deleted / locked, by the Blogger spam classifier - which the owners want restored.

If properly requested by a former owner, we may request review of a blog, that appears to be improperly classified.

We sample the Blogger spam population, using forum spam reviews.

To request review, we submit a blog in a database. The database is read by the Google staff, which hand review blogs classified by the automated processes.

Having submitted a handful of review requests, we wait for the review results. The results of the reviews provide a sample, of blogs being classified, and reviewed.

Seeing a trend of spam review results, we observe what is being classified.

The general trend would be between 33% and 66% of righteous / spurious spam classification ratio (in other words, varying between a 1/2 to a 2/1 ratio). Instinctively, that should be normal - since Blogger tries to get as many spammers out of business - but without disturbing too many legitimate blog owners.

Occasionally, we see the ratio more like 1/9 - or 9/1. Then, we see a predominance of one or two classes of blogs, as reviewed.

  1. Blogs not spam.
  2. Blogs marginally spammy.
  3. Blogs blatantly spammy.

Currently, we are seeing more legitimate blogs, being spuriously classified.

Most recently, we saw a large population of Groups #1 and #2. When review was requested, 95% of those submitted were restored.

There will always be some spam blogs, not classified - that should be. And there will always be some blogs spuriously classified - that should not be.

But when the majority of the blogs for which review is requested, are subsequently restored, that tells us that the Blogger spam classifiers are having to reach deeper into Groups #1 and #2, above. And that implies that Group #3 is becoming smaller. And that Group #3 includes less blogs which blatantly imitate Group #1.

There will always be spammers, trying to discourage spam reviews.

In spite of the devious maligning of the Blogger spam mitigation policies

The Blogger system of preventing spam is full of failures - and the support team don't remove blogs with spam/malware/nudity and other offenses.

We can tell, from the samples, that the system is working. And that of the people who suggest the negatives

The Blogger system of preventing spam is full of failures - and the support team don't remove blogs with spam/malware/nudity and other offenses.

many of them are non self aware spammers, who are lamenting loss of their blogs.

People who want spam classification improved have to request review.

If spam filter tuning is to continue successfully, everybody who is not a spammer, but who is treated as if they are, must request review of their blogs. And the majority of the review requests must produce blogs restored - which gives Blogger details to tighten the filters, and classify less blogs that are legitimate, during the next classification cycle.

Blogger can't tune their filters based upon non responding legitimate blog owners. People who post
My blogs were deleted - but I'm not providing the URLs, because the Blogger anti-spam policies don't work!

  • Are spammers, trying to discourage the spam classification and review process.
  • Are non spammers who will, unfortunately, never see their blogs again.

Which group each blog owner falls into, remains to be seen. If your blog was recently classified, and you believe classification was unfair, then you have to submit your blog for review.

Adding A Link To Your Blog Post

Occasionally, you see a very odd, cryptic complaint I just added a link in my blog, but the link vanished! No, it wasn't your imagination.

What's The URL Of My Blog?

We see the plea for help, periodically I need the URL of my blog, so I can give it to my friends. Help! Who's buried in Grant's Tomb, after all? No Chuck, be polite. OK, OK. The title of this blog is "The Real Blogger Status", and the title of this post is "What's The URL Of My Blog?".

Embedded Comments And Main Page View

The option to display comments, embedded below the post, was made a blog option relatively recently. This was a long requested feature - and many bloggers added it to their blogs, as soon as the option was presented to us. Some blog owners like this feature so much, that they request it to be visible when the blog is opened, in main page view. I would like all comments, and the comment form, to be shown underneath the relevant post, automatically, for everyone to read without clicking on the number of comments link. And this is not how embedded comments work.
