would there be an option to look into the votes being held by dead witnesses and maybe find a way to return these to the voter if a witness is not active for X amount of time?
Some of these are seemingly still assigned blocks and this has a few disadvantages:
If they are listed in the top 50 they are voted on by new users that have no idea a witness is no longer active
does assigning non active blocks not cause potential delays in handing them over?
These votes would then be able to be re assigned to new projects that can all use a bit more support.

I am part of a new team that started @swisswitness a while back and I have found this a big topic among other witnesses I have spoken to.
