Suggesting to add a 'I am writing about myself, my friend, or employer (required to disclose)' tick box at the account creation page. When ticked, it shows three things
- a select box that asks to choose
- about myself
- about my company
- about my friend
- about my employer
- Text box to input name of what article they're editing or creating
- a tick box 'I am paid for my writing'
Then this information is used to
- automatically generate the COI banner at the user page, and
- automatically add an extra note to the welcome message at their talk page, saying "Please don't edit article about XXXXX directly. Use edit request at talk page. If writing a draft, please ask to do a references check (per [[WP:NOTABILITY]]) when the article is small (1-2 paragraphs long) before expanding it further."
The message should be configurable per-wiki.
