Google-chrome – Wikipedia Spam Filter Notice

By bypassing the spam filter with creating your own label, you are taking away Gmail's learning capabilities. There is probably a reason your emails are getting filtered as spam (lots of images, certain keywords, etc.)

I would suggest going back to the default: taking off your custom spam filter, placing all the known spam into the spam box by hitting the "Report Spam" button, and keeping an eye on the spam box for a while.

There is a download available for all pages in the article namespace of the English language wikipedia which is located at:

http://dumps.wikimedia.org/enwiki/latest/enwiki-latest-all-titles-in-ns0.gz

However they do not generate this kind of list for every language, so you need to create it yourself from the all content dump. See the full list of all available dumps (just change the en-part of the URL to the language you want to see).
