 * ClueBot NG makes very few mistakes, but it does happen. If you believe the change you made was constructive, please read about it, [ report it here], remove this message from your talk page, and then make the edit again.

 * In the case of your unexplained removal of Karymshina, I think cluebot got it right. If you wish to removed cited material then you could at least say so in the edit summary and really, you need to say why with a VERY good reason. Op47 (talk) 00:09, 2 October 2015 (UTC)

Wikipedia and copyright
Hello Siyu Lai, and welcome to Wikipedia. Your addition to Krakatoa has had to be removed, as it appears to have added copyrighted material without permission from the copyright holder. While we appreciate your contributing to Wikipedia, there are certain things you must keep in mind about using information from your sources to avoid copyright or plagiarism issues here.


 * You can only copy/translate a small amount of a source, and you must mark what you take as a direct quotation with double quotation marks (") and a cited source. You can read about this at Non-free content in the sections on "text". See also Help:Referencing for beginners, for how to cite sources here.
 * Aside from limited quotation, you must put all information in your own words and structure, in proper paraphrase. Following the source's words too closely can create copyright problems, so it is not permitted here; see Close paraphrasing. (There is a college-level introduction to paraphrase, with examples, hosted by the Online Writing Lab of Purdue.) Even when using your own words, you are still, however, asked to cite your sources to verify information and to demonstrate that the content is not original research.
 * Our primary policy on using copyrighted content is Copyrights. You may also want to review Copy-paste.
 * If you own the copyright to the source you want to copy or are a designated agent, you may be able to license that text so that we can publish it here. However, there are steps that must be taken to verify that license before you do. See Donating copyrighted materials.
 * In very rare cases (that is, for sources that are public domain or compatibly licensed), it may be possible to include greater portions of a source text. However, please seek help at the help desk before adding such content to the article. 99.9% of sources may not be added in this way, so it is necessary to seek confirmation first. If you do confirm that a source is public domain or compatibly licensed, you will still need to provide full attribution; see Plagiarism for the steps you need to follow.
 * Also note that Wikipedia articles may not be copied or translated without attribution. If you want to copy or translate from another Wikipedia project or article, you can, but please follow the steps in Copying within Wikipedia.

It's very important that contributors understand and follow these practices, as policy requires that people who persistently do not must be blocked from editing. If you have any questions about this, you are welcome to leave me a message on my talk page. Thank you. Doug Weller (talk) 21:31, 30 October 2015 (UTC)

Hello, I'm Kendall-K1. I wanted to let you know that I undid one or more of your recent contributions to Krakatoa because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.
 * Similar for 946 eruption of Paektu Mountain and Volcanic Winter. IF YOU REMOVE MATERIAL ON THIS SCALE. YOU MUST EXPLAIN WHY. This is the second time that I have had to write to you on this matter. Op47 (talk) 19:08, 31 October 2015 (UTC)
 * You also re-instated a faulty edit at La Garita Caldera as being a minor edit. I am not questioning you knowlege of volcanos, but your English meas your edits need a certain amount of copy editing. If you don't mark your edits as minor edits then at least native English speakers have an opportunity to know you have made an edit and can make adjustments as needed.Op47 (talk) 19:35, 31 October 2015 (UTC)

You have been blocked indefinitely from editing for violating copyright policy by copying text or images into Wikipedia from another source without verifying permission. You have been previously warned that this is against policy, but have persisted.

Please take this opportunity to be sure you understand our copyright policy and our policies regarding how to use non-free content. If you think there are good reasons why you should be unblocked, you may appeal this block by first reading the guide to appealing blocks, then adding the following text to the bottom of your talk page:.

Clarifying your block
You continued to add copyright material after I warned you. In addition, you removed material from other articles without explanation. You did change the copyright material slightly but the difference was tiny and in some cases introduced poor English.

What you need to do now, either here or on your userpage, is find some of your copyvio and show us how you would rewrite it in your own words. Doug Weller (talk) 16:42, 14 November 2015 (UTC)
