To begin, let me state for the record that I am not the artist known as Banksy. My name is Shone Brooks. I try to contribute meaningfully when I see the opportunity to do so. I am a volunteer and despite unfounded allegations by a select few, well meaning, but unduly aggressive WP editors, I have never, EVER received any compensation for any of my WP contributions. Mindful of the need to avoid conflict of interest, I try my best to put the goals of Wikipedia ahead of other considerations that arise when editing articles. If any of my edits cause heartburn, let's talk it over, friend. There's always room for improvement, right?
The idea of "owning" a Wikipedia article is largely inaccurate. Editors collaborate to continually improve the articles found in Wikipedia. Perhaps the closest you can come to "owning" an article is to be the person who created the initially published version. Many draft articles never see the light of day. Here is a short list of my creations that I'm pleased to say "made the cut," were published, and remain so.
