I was also about to comment about their price feed update and I'm glad that someone already did. I hope someone who is responsible for the witness is reading about this. Currently, I'm also voting Leofinance but I also notice that I'm voting a few more witnesses who are not updating their feed price.
I guess there is a simple script available that is being used by many witnesses already to update price feed regularly. It shouldn't be very hard to keep that script running to do the task.
