142 Pages

Of approximately 18,000 English wikis created between 22 July and 31 August, 3,468 (19.2%) of them contained at least one external link in mainspace or user blog space. All 1161 spam wikis contained an external link (100%), and 2307 of 17,000 presumed "good" wikis contained an external link (13.6%). The rest of the report considers only wikis with external links, since the number of spam wikis without an external link is negligible.

## Country of origin

This compares the country in which the wiki was created (found via CheckUser and ip-api.com). Obviously I can't CheckUser a few thousand safe wikis just to get a baseline of the wiki creation breakdown, so I used the stats for wikia.com on Quantcast, averaging the unique and pageview percentages because I really have no idea which would be a better indicator of wiki creation. The Quantcast stats may or may not be reliable, but they match my initial assumptions fairly well. Surprisingly or not, the four main South Asian countries (Bangladesh, India, Pakistan, Philippines) make up about 60% of the spam wikis even though they only account for 3-5% of total Wikia traffic. Based solely on a Bayesian interpretation of this data, the fact that a wiki has an external link and was made in India gives it a $\frac{7% \times 100% \times 46.02%}{7% \times 100% \times 46.02% + 93% \times 13.57% \times 0.94%} = 96.45%$ chance of being spam. My country data would have to be off by a factor of 6 for that chance to be below 80% in reality.

## Keywords

Note: keywords are not part of the filter yet.

Looks at the number of times a keyword shows up in spam wikis versus non-spam wikis. I looked at 5624 spam wikis and 2206 non-spam wikis, and then ignored 338 specific Romanian spam wikis that were throwing off the top 250 list. To "normalize" the factors, I added one to each word bucket before dividing, so there would be no division by zero. Clearly a lot of the top non-spam ones have to do with formatting and regular wiki-related things -- there isn't going to be a spam wiki that uses an infobox.
