Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Tharakan (Hindu caste), it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. R.C Outlander07@talk 10:27, 26 July 2021 (UTC)

Hello, I'm Yamaguchi先生. I noticed that you added or changed content in an article, Sankarapuram, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Yamaguchi先生 (talk) 19:50, 18 July 2023 (UTC)

Please do not add or change content, as you did at Sankarapuram, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Please refrain from adding content to any Wikipedia article if you don't have a valid, reliable third party source for the same. Yamaguchi先生 (talk) 23:35, 18 July 2023 (UTC)
