Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, your addition of one or more external links to the page Optical projection tomography has been reverted. Your edit here to Optical projection tomography was reverted by an automated bot that attempts to remove links which are discouraged per our external links guideline. The external link(s) you added or changed (http://www.youtube.com/watch?v=-PCWI-fX7Ss, http://www.youtube.com/watch?v=LbbLWsbFLXY&feature=related) is/are on my list of links to remove and probably shouldn't be included in Wikipedia. If the external link you inserted or changed was to a media file (e.g. a sound or video file) on an external server, then note that linking to such files may be subject to Wikipedia's copyright policy, as well as other parts of our external links guideline. If the information you linked to is indeed in violation of copyright, then such information should not be linked to. Please consider using our upload facility to upload a suitable media file, or consider linking to the original. If you were trying to insert an external link that does comply with our policies and guidelines, then please accept my creator's apologies and feel free to undo the bot's revert. However, if the link does not comply with our policies and guidelines, but your edit included other, constructive, changes to the article, feel free to make those changes again without re-adding the link. Please read Wikipedia's external links guideline for more information, and consult my list of frequently-reverted sites. For more information about me, see my FAQ page.

Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added to the page Steganography 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. Spacexplosion[talk] 19:32, 31 January 2012 (UTC)

Please do not add inappropriate external links to Wikipedia, as you did to Steganography. 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 article, please discuss it on the article's talk page rather than re-adding it. * --- Barek (talk • contribs) - 21:56, 31 January 2012 (UTC)

Please stop adding inappropriate external links to Wikipedia, as you did to Steganography. 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. --- Barek (talk • contribs) - 22:20, 31 January 2012 (UTC)

Hi, can you tell me in brief where is the external link in what I am adding? This is a journal paper on Steganography and very highly cited. I failed to understand why do you call it inappropriate?

Steganography, cryptography and watermarking could be differentiated based on their objectives, requirements, and the relation to the carrier file.
