The long term preservation of fanworks seems like a weird thing to do because it seems like very few entities in the creator world seem interested in preserving canonical works for very long, unless they're still profitable to run and rerun. The hustle part of it is for people who want to try and stay at the top of the new works page for audience exposure and possibly to try and get some monetization of of their fanwork.

Honestly, it's a recipe for burnout, and I think that's the point where archiving is most needed and least likely to happen.
