Thread:Project:Support desk/Are there Advertisements or Pop-ups on Mediawiki pages?/reply (2)

As Mark pointed out, if your wiki is publicly accessible from the internet, Spam can reach your wiki if you don't have any restrictions or filters in place.

However I think you were asking whether MediaWiki itself contains any advertisements by default. The answer is no. MediaWiki is not shareware, freeware, or adware. MediaWiki is open-source and free software (FOSS). Aside from any extra features installed on mediawiki.org (which you can install as well), what you see here is exactly what you get when you install it. There are no advertisements!
