Not my job. Sites not controlled by me will eventually disable or delete things. Sites controlled by me will self delete once funding dries up. If I have done things according to my plans most proof I existed will be gone.
After that, I have strict requirements (and instructions) in my estate for accessing and deleting the few accounts I still need at that time. I'm fortunate enough to have started using a password manager as early as 15 years ago, and used it diligently, so redundant access is as easy as possible.
I have a “death instruction manual” document with all the data and information my wife will need to access my digital life, including the documentation mentioned above, and contact information for people I trust to help her through the process of either managing those servers, or selling them for a good amount of money (there is about 90TB of storage in those).
I also try to teach her, and in time my son (he is too young right now), to manage those servers, but that is more of a long-term goal. She’s comfortable with Linux, so that’s a start.
