I already start to think that, with the existence of Rule34 and E621, it allows us to understand that if the artist is no longer active, then Rule34 and E621 is a best option to become a equivalent of Alexandria. I start thinking this because i saw something very important when it comes to preserving art. I recently made a "Am i too Paranoid" post because i can't stop thinking about the future of Online Arts, what's the future is looks like, is the artist gonna destroy or NUKED their own work, or other things.
