The modern notion of a website with user accounts stems from like 2000 and many of those websites are still in use. Over the course of 25 years, some number of people die. That is a thing that occurs. Websites do not understand death. Websites are a four year old child and they believe this user just hasn't signed on in awhile, and will someday come back. Websites are constantly attempting to involve dead people in activities. At a certain point, four-year-old behavior stops feeling cute.
