Hello, I'm Hzh. I noticed that you added or changed content in an article, Green Day discography, 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.

You are suspected of sock puppetry, which means that someone suspects you of using multiple Wikipedia accounts for prohibited purposes. Please make yourself familiar with the guide to responding to investigations, then, if you wish to do so, respond to the evidence at Wikipedia:Sockpuppet investigations/Никита-Родин-2002. Thank you.
