Blogger Filtering for Spam Blogs
Blogger has put into place some powerful automated spam detection into its algorithms. Which will automatically classify blogs with repetitive words and tons of links pointing to a single website as spam. However, in the event that Blogger inadvertently marks your legitimate blog as spam in its zeal to filter out trashy sites, there are steps that you must take within 20 days to avoid your blog from being deleted altogether. It is crucial that you read this article on How to Fix a Mistakenly Marked as Spam Blog.
However, if you still do happen to come across a blog on Blogger that fits the criterias of spam, Blogger has enabled you to manually flag the blog. This helps to reduce the clutter in the blogosphere and enable Google to always return the most relevant high quality sites in the search results.
You can flag a spam blog by following these 3 easy steps.
1) Flag the spam blog by clicking on the Report Abuse link on the top navigation bar, just beside the search box.
2) In the Report a Terms of Service Violation page, select the type of violation from the list that you would like to report. Essentially, there are eight types of violations, including defamation/libel/slander, copyright/piracy issues, spam, nudity, hate or violence, impersonation, or if someone is posting your private information on the blog or that someone else is using your account. There is a Learn More link there, with more explanations as to what each violation means. Click Continue once you have selected the offence.
3) It will automatically take you to the Report a Spam Blog page, with the url link of the offending blog pre-filled in the blank. All you have to do is click Submit. You only need to do this once.
Once that is done, you will see a thank you note and Blogger will examine the issue and take action as necessary.
