The first and primary duty of witnesses should be to produce blocks.
I just looked, Leofinance hasn't been producing blocks for a week. He withdrew from Witnesses. Hive's development and recognition worked hard. It created and maintains one of the most active communities. Despite this, I didn't vote for Leofinance as a witness. I think it deserved a witness vote. Thank you for your efforts and hard work for Hive.
There is a witness who last updated the Hive price 4 years ago and is in the top 30. I think this situation is also surprising.
A lot of witnesses don't take running a price feed serious and believe it is optional.
