Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added to the page Coal do not comply with our guidelines for external links and have been removed. Wikipedia is not a collection of links; nor should it be used as a platform for advertising or promotion, and doing so is contrary to the goals of this project. Because Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, please discuss it on the article's talk page before reinserting it. Please take a look at the welcome page to learn more about contributing constructively to this encyclopedia. Thank you. Old Moonraker (talk) 19:15, 10 June 2011 (UTC)

If this is a shared IP address, and you didn't make the edit, consider creating an account for yourself so you can avoid further irrelevant notices.

This is your last warning. The next time you insert a spam link, as you did at

• Titanium dioxide ‎,
• Bioplastic,
• Coal,
• Solar thermal energy,

you may be blocked from editing without further notice. 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. Jojalozzo 21:30, 23 February 2012 (UTC)

Please do not add inappropriate external links to Wikipedia, as you did to Phosphor. 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 web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site 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. Thank you. Materialscientist (talk) 22:19, 4 February 2013 (UTC)

You have been blocked temporarily from editing 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 why you should be unblocked, you may appeal this block by adding below this notice the text {{unblock|reason=Your reason here ~~~~}}, but you should read the guide to appealing blocks first.
