Hello, I'm Materialscientist. I noticed that you made a change to an article, 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! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

This is your only warning; if you vandalize Wikipedia again, as you did at 44th G7 summit, you may be blocked from editing without further notice. Zingarese (talk) 23:19, 14 June 2018 (UTC)

You have been blocked from editing for a period of 2 weeks for persistent vandalism. Once the block has expired, you are welcome to make useful contributions. If you think there are good reasons for being unblocked, please read the guide to appealing blocks, then add the following text below the block notice on your talk page:.
