Hello, I'm Walter Görlitz. I wanted to let you know that one or more external links you added to Acceptance testing have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.

You may be blocked from editing without further warning the next time you insert a spam link. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines.

Please stop adding inappropriate external links to Wikipedia, as you did to Machine learning. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
