Blogspot is more spam than blogs. Or any one or more of the following:
- Blogspot has become nothing but a crapfarm
- 90% of all blogspot com subdomains are junk
- Has Google stopped helping in the fight against splogs
- Blogspot is currently broken
- Maybe Google Inc is or was* merely naive when it comes to splogs. They allow one-click publishing…
However, no one ever posts numbers for their theories, so I’ll do a quick sample, just like from a statistics textbook on binary distributions.
I chose to browse 50 Google Blogger blogs at Blogspot, looking for any that might be splogs. I use their random blog link, which I will assume to be truly random. I keep track of four variables: last update, front-page size (wordcount), splog or not, and adsense or not. Here is the raw data in xls format:
The rough descriptive statics, where 1 means total spam and 0 means totally clean, are:
Variable N N* Mean SE Mean StDev
splog 50 0 0.2800 0.0641 0.4536
This bar chart should give you a better idea:
Yes, approximately 72% of Blogspot blogs are real. The other 28% are spam blogs, or splogs. And, we can give a bound, by the central limit theorem, on the accuracy of this experiment. A 95% CI for a single-sample proportions test is (0.162311, 0.424905), with a p-value 0.003.
