All of these errors were within the past 15 days. I chose 5 random obstroller sites and checked these reports and these errors popped up. There are likely additional errors that weren't picked up by my script. The FAA wants to replace us. In our place would be these people putting out reports likely similar in quality to the ones I've listed.
