`  == Borders edit and the VandalProof tool ==  You recently wrote on my talk page: ``It might not have been your intention, but your recent edit removed content from Borders Group. Please be careful not to remove content from Wikipedia without a valid reason, which you should specify in the edit summary or on the article's talk page. Take a look at our welcome page to learn more about contributing to this encyclopedia. Thank you. A link to the edit I have reverted can be found here: link. If you believe this edit should not have been reverted, please contact me``  Before my edit, the Borders Group page was in both the Category:1971 establishments and Category:Companies established in 1971 (a direct subcategory of the former category).  After my edit the Borders page was only in the Category:Companies established in 1971.  Generally, articles should not be placed in a cat and the cat's parent cat (I see no good reason to make an exception here).  The reason for this is to reduce category clutter which helps readers find what they're looking for.  I am concerned that your  tool is not well configured.  If you compare the message on my talk page with the facts: *``It might not have been your intention, but your recent edit removed content from ...`` - it was my intention - I said so in the edit summary. *``be careful not to remove content from Wikipedia without a valid reason`` - I had a valid reason. *``which you should specify in the edit summary `` - I did specify in the edit summary. *``Take a look at our welcome page to learn more about contributing to this encyclopedia`` - I am a well-established editor - Check my edit history, edit count, talk page etc.  I appreciate that you are trying to deal with the problem of vandalism and I understand why you have constructed the talk page message the way you have.  However, please consider that that for editors who are not vandals, did use the edit summary and are not total newbies the above message is rather patronising.  I suggest that you need to make the tool more discriminating (well established editors are not likely to be vandals) and work on the user notification.   `
