Hello, I'm The Banner. I noticed that you added or changed content in an article, Irish people, 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 the tutorial on citing sources, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. The Banner talk 18:32, 7 February 2020 (UTC)

What was unreadable about the source I used?

Unsourced
You seem to have a serious issue with the concept of "unsourced" (= no new sources given for your addition). You better work on that. The Banner talk 19:12, 7 February 2020 (UTC)
