Some spam was added to the wikidata-repo yesterday.

Here are a few regexes that can be added to the MediaWiki:Spam-blacklist:

\bmusic-software-programs\.com\b
\btwitter\.com/#!/(software_music|licensing_music)\b

\blicensing-of-music\.com\b

\bpaydayloansonline0\.com\b

I am an beginner in writing regexes though.
