Please do not add inappropriate external links to Wikipedia, as you did to Decision tree pruning. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it. [1] MrOllie (talk) 17:04, 20 February 2022 (UTC)

Please stop your disruptive editing. If you continue to add inappropriate external links to Wikipedia, you may be blocked from editing. 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.

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.

You have been blocked from editing for a period of 3 days for adding spam links. Persistent spammers will have their websites blacklisted from Wikipedia and potentially penalized by search engines. Once the block has expired, you are welcome to make useful contributions.

If you think there are good reasons for being unblocked, please read the guide to appealing blocks, then add the following text below the block notice on your talk page: {{unblock|reason=Your reason here ~~~~}}.  Alexf^(talk) 20:25, 20 February 2022 (UTC)
