I had a domain that I was just using for e-mail, just to catch everything and not link directly to me. Then lent the A record to host an archive of something, which got linked around a load of places. So had "SEO Value" suddenly.
Did the same, the renewal failed because the card had expired, and now squatters have been sat on it, probably getting all my spam and resetting my credentials on random websites for the last 10 years.
