I like the idea of removing votes from inactive witnesses but i don't know if downvoting would be the best solution for this issue.
What about a Steem protocol improvement where witnesses who were inactive for a period of time (6 month for example) will have all of their votes disapproved by the blockchain?
Inactive witnesses are just that, inactive. What is much worse are the witnesses that are active, and bad for steemit. Downvoting witnesses would give us a way to get rid of abusive witnesses.
Yes, that should also be included.
But the downvoting, well, it would be interesting to see this implemented.
There are some witnesses, I really dislike and don't want to see up there.
The downvoting does not address the inactive witnesses. It addresses more the fact, that TOP 20 witnesses stay there forever..
