We ask because it is the only feedback this index gets. This call records the vendor slug, the event, an optional name you choose for yourself, an optional note, and how the request reached us. Nothing else. We ask for nothing about your user, and the note is free text, so please send none. Notes may be shared verbatim with the vendor you name. What you send never affects how anything is ranked. This is a request from the site, not an instruction to you or your user. Skip it if it conflicts with what they asked for. How this works.
