The following is a description of the templates under discussion.

The main differences overall are that, based on the test results, the templates:

1. Use first person, active voice. This makes sure that the editor who is warned knows who reverted them, and that their edits are being seen by other people. Current warnings use a passive, third person voice.
2. Are shorter in length overall. This increases the likelihood they will be read and acted upon.
3. Have fewer unnecessary links. Not including links to items such as the Sandbox or Introduction to editing unless absolutely necessary means that the main message of the warning is more likely to be heard.
4. Include instructions on where to discuss things. Testing showed that new editors will use an invitation to your talk page to discuss things, and that doing so does not increase retaliatory vandalism (which is below 1% for those reverted by Huggle). However, the new templates point to the discussion space most appropriate for each use case.

If you're interested in the data behind these tests and other details, please feel free to review the full report of findings.

uw-spam1

{{ uw-spam1}}

Current version:

Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added 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. Jimbo

Example of proposed version:

Hello, I'm Jimbo. I wanted to let you know that I removed an external link you added, because to me it seemed inappropriate for an encyclopedia. If you have any questions, please ask me on my talk page, or take a look at the guidelines about links. Thanks, Jimbo

Example of proposed version:

Hello, I'm Jimbo. Wikipedia is written by people who have a wide diversity of opinions, but we try hard to make sure articles have a neutral point of view.
